It is also noted that: Each cluster at least consists of one data object. Hence, the aim of the partition based clustering algorithm is to determine the K number of cluster centers in a given dataset. Here, the MCSS algorithm is applied for determining the optimal cluster centers in a dataset.
Clustering has proven its importance in many applications successfully.

Some of these are pattern recognition [ 1 , 2 ], image processing [ 3 — 6 ], process monitoring [ 7 ], machine learning [ 8 , 9 ], quantitative structure activity relationship [ 10 ], document retrieval [ 11 ], bioinformatics [ 12 ], image segmentation [ 13 ], construction management [ 14 ], marketing [ 15 , 16 ] and healthcare [ 17 , 18 ]. Broadly, clustering algorithms can be divided into two categories - partition based clustering algorithms and hierarchal clustering algorithms.
In partition based clustering algorithms, partition a dataset into k clusters on the basis of some fitness functions [ 19 ]. While in hierarchical clustering algorithms, clustering of data occurs in the form of tree representation and this representation is known as dendrogram. Hierarchical clustering algorithms do not require any prerequisite knowledge about number of clusters in a dataset but its only drawback is lacking of dynamism as the objects are tightly bound with respective clusters [ 20 — 23 ].
However, our research is focused on partition clustering, which decomposes the data into several disjoint clusters that are optimal in terms of some predefined criteria. From the literature, it is found that K-means algorithm is the oldest, most popular, and extensively used partition based algorithm for data clustering. It is easy, fast, simple structure, and having linear time complexity [ 24 , 25 ]. In K-means algorithm, a dataset is decomposed into a predefined number of clusters and the data into distinct clusters based on the euclidean distance [ 25 ].
Nowadays, heuristic approaches gain wide popularity to solve the clustering problem and become more successful. Numerous researchers have been applying heuristic approaches in the field of clustering. Some of these are summarized as simulated annealing [ 26 ], tabu search [ 27 , 28 ], genetic algorithm [ 29 — 32 ], particle swarm optimization [ 33 , 34 ], ant colony optimization [ 35 ], artificial bee colony algorithm [ 36 , 37 , 56 ], charged system search algorithm [ 38 , 39 ], cat swarm optimization [ 40 — 42 , 57 ], teacher learning based optimization method [ 43 , 44 ], gravitational search algorithm [ 45 , 46 ] and binary search based clustering algorithm [ 47 ].
The magnetic charged system search MCSS algorithm is a recent meta-heuristic algorithm based on electromagnetic theory [ 48 ]. According to electromagnetic theory, moving charged particles produce an electric field as well as a magnetic field. Movement of the charged particles in a magnetic field enforces a magnetic force on the other charged particles and the resultant force is proportional to the charge mass and speed of the charged particles.
The magnitude and direction of the resultant force depend on the two factors: first, velocity of the charged particles, and secondly, magnitude and direction of the magnetic field. Along this, MCSS can be either attractive or repulsive in nature. This nature of MCSS algorithm generates more promising solutions in random space.
On the other hand, CSS algorithm is attractive by nature.

Thus, the performance of the algorithm can be affected with small number of CPs. So, the addition of the magnetic force to the already existing electric force, results in enhancement of both the exploration and exploitation capabilities of CSS and this makes the algorithm more realistic one. Hence, the inclusion of magnetic force in the charge system search CSS algorithm results in the formation of a new algorithm known as magnetic charge system search MCSS.
The main steps of the MCSS algorithm are as follows. Algorithm starts by identifying the initial positions of charged particles CPs in d-dimensional space in random order and set the initial velocities of CPs is zero. To determine the initial positions of CPs, equation 1 is used. A variable charge memory CM is used to store the best results. The total force is the combination of the electric force and magnetic force, and this force influences the movement of CPs in d-dimensional space. It can be computed as follows: Determine the electric force — when CPs move in d-dimensional space, an electric field is produced surrounding it, and exerted an electric field on the other CPs.
This electric force is directly proportional to the magnitude of its charge and the distance between CPs. The magnitude of an electric force generated by a charge particle is enforced on another charge particle and it can be measured using equation 2. In equation 2 , q i and q k represents the fitness values of i th and k th CP, r ik denotes the separation distance between i th and k th CPs, w 1 and w 2 are the two variables whose values are either 0 or 1, R represents the radius of CPs which is set to unity and it is assumed that each CPs has uniform volume charge density but changes in every iteration, and P ik denotes the moving probability of each CPs.
Determine the magnetic force — The movement of CPs also produce magnetic field along with the electric field. As a result of this, a magnetic force is imposed on the other CPs and equation 3 is utilized to compute the magnitude of magnetic force exerted by a CP on other CPs. It can be either positive or negative depending on the value of average electric current of the previous iteration.
In equation 3 , q k represents the fitness values of the k th CP, I i is the average electric current, r ik denotes the separation distance between i th data instance and k th CPs, w 1 and w 2 are the two variables whose values are either 0 or 1, R represents the radius of CPs which is set to unity, and PM ik denotes the probability of magnetic influence between i th data instance and k th CP.
In other words, it can be summarized that the magnetic force can be either attractive or repulsive in nature. As a result of this, more promising solutions can be generated during the search. Whereas, the electric force is always attractive in nature. Therefore, this nature of electric force may influence the performance of the algorithm. Hence, to overcome the repulsive nature, a probability function is added with the electric force and finally, the total force acting on other CPs can be computed using equation 4.
Where, p r denotes a probability value to determine either the electric force E ik repelling or attracting, E ik and M ik present the electric and magnetic forces exerted by the k th CP to i th data instance. Newton second law of motion is applied to determine the movement of CPs. The magnitude of the total force with Newtonian laws is used to produce the next positions and velocities of CPs. The new positions and velocities of CPs can be computed using equation 5 and 6. If the maximum iterations is reached and condition is satisfied, then stop the algorithm and obtain the optimal cluster centers.
Otherwise repeat steps 2—4. This section summarizes the pseudo code of the MCSS algorithm for clustering tasks. Step 3: Compute the value of objective function using equation 7 and arrange the data instances to the clusters using minimum value of objective function.
Step 7. Step 9: Calculate the new positions and velocities of charged particles using equation 5 and 6. Step Recalculate the value of objective function using new positions of charge particles. Step Compare the newly generated charge particles to the charge particles reside in CM. This section deals with the experimental setup of our study. It includes the performance measures, parameters settings, datasets to be used, experiment results, and statistical analysis. To prove the effectiveness of the MCSS algorithm, 10 datasets are applied in which two datasets are artificial ones and the rest are taken from UCI repository.
The performance of MCSS algorithm is examined over the sum of intra cluster distance and F-measure parameters. The sum of intra cluster distance can be measured in terms of best case, average case, and worst case solutions including standard deviation parameter which shows the dispersion of the data. F-measure parameter is used to measure the accuracy of proposed method. Performance measures are described as follows:.
Intra cluster distance can be used to measure the quality of clustering [ 35 , 36 ]. It indicates the distance between the data objects within a cluster and its cluster center. His future aspirations include developing analytics tools that combine novel machine learning methods with the emerging field of computational rhetoric for monitoring and interpreting online information in various application areas in real-time.

Fan, W. Seref, Y. Seref, W. Chaovalitwongse, J. Seref, J. Brooks, S. Seref, C. Seref, P. Seref, R. Ahuja, J. Seref, O. Kundakcioglu, O. Prokopyev, P. Cifarelli, M. Seref, S. Cuciniello, P. Guarracino, C. Cifarelli, N. Xanthopoulos, T. Brooks, B. It presents methods for data input and output as well as database interactions. The author also examines different facets of string handling and manipulations, discusses the interfacing of R with other languages, and describes how to write software packages. He concludes with a discussion on the debugging and profiling of R code.
Data Manipulation with R. The ready availability of the program, along with a wide variety of packages and the supportive R community make R an excellent choice for almost any kind of computing task related to statistics. However, many users, especially those with experience in other languages, do not take advantage of the full power of R. Because of the nature of R, solutions that make sense in other languages may not be very efficient in R. This book presents a wide array of methods applicable for reading data into R, and efficiently manipulating that data.
All of the methods presented take advantage of the core features of R: vectorization, efficient use of subscripting, and the proper use of the varied functions in R that are provided for common data management tasks. Most experienced R users discover that, especially when working with large data sets, it may be helpful to use other programs, notably databases, in conjunction with R. Accordingly, the use of databases in R is covered in detail, along with methods for extracting data from spreadsheets and datasets created by other programs.
Character manipulation, while sometimes overlooked within R, is also covered in detail, allowing problems that are traditionally solved by scripting languages to be carried out entirely within R. For users with experience in other languages, guidelines for the effective use of programming constructs like loops are provided. Since many statistical modeling and graphics functions need their data presented in a data frame, techniques for converting the output of commonly used functions to data frames are provided throughout the book.
Using a variety of examples based on data sets included with R, along with easily simulated data sets, the book is recommended to anyone using R who wishes to advance from simple examples to practical real-life data manipulation solutions. Springer, New York, 2nd edition, This book not only introduces the reader to this topic but enables him to conduct the various unit root tests and co-integration methods on his own by utilizing the free statistical programming environment R. The book encompasses seasonal unit roots, fractional integration, coping with structural breaks, and multivariate time series models.
The book is enriched by numerous programming examples to artificial and real data so that it is ideally suited as an accompanying text book to computer lab classes. The second edition adds a discussion of vector auto-regressive, structural vector auto-regressive, and structural vector error-correction models. To analyze the interactions between the investigated variables, further impulse response function and forecast error variance decompositions are introduced as well as forecasting. The author explains how these model types relate to each other.

The book has received endorsements from top econometricians. Wavelet Methods in Statistics with R. This book fulfils three purposes. First, it is a gentle introduction to wavelets and their uses in statistics. Second, it acts as a quick and broad reference to many recent developments in the area.
The book concentrates on describing the essential elements and provides comprehensive source material references. Third, the book intersperses R code that explains and demonstrates both wavelet and statistical methods. The code permits the user to learn the methods, to carry out their own analyses and further develop their own methods. The book is designed to be read in conjunction with WaveThresh4, the freeware R package for wavelets.
The book introduces the wavelet transform by starting with the simple Haar wavelet transform and then builds to consider more general wavelets such as the Daubechies compactly supported series. The book then describes the evolution of wavelets in the directions of complex-valued wavelets, non-decimated transforms, multiple wavelets and wavelet packets as well as giving consideration to boundary conditions initialization. Later chapters explain the role of wavelets in nonparametric regression problems via a variety of techniques including thresholding, cross-validation, SURE, false-discovery rate and recent Bayesian methods, and also consider how to deal with correlated and non-Gaussian noise structures.
The book also looks at how nondecimated and packet transforms can improve performance. The penultimate chapter considers the role of wavelets in both stationary and non-stationary time series analysis. The final chapter describes recent work concerning the role of wavelets for variance stabilization for non-Gaussian intensity estimation.
The book is aimed at final year undergraduate and Masters students in a numerate discipline such as mathematics, statistics, physics, economics and engineering and would also suit as a quick reference for postgraduate or research level activity. The book would be ideal for a researcher to learn about wavelets, to learn how to use wavelet software and then to adapt the ideas for their own purposes.
This is a book written in colloquial language, avoiding mathematical formulae as much as possible, trying to explain statistical methods using examples and graphics instead. To use the book efficiently, readers should have some computer experience. The book starts with the simplest of statistical concepts and carries readers forward to a deeper and more extensive understanding of the use of statistics in environmental sciences. The book concerns the application of statistical and other computer methods to the management, analysis and display of spatial data.
These data are characterised by including locations geographic coordinates , which leads to the necessity of using maps to display the data and the results of the statistical methods. Although the book uses examples from applied geochemistry, and a large geochemical survey in particular, the principles and ideas equally well apply to other natural sciences, e.
The book is unique because it supplies direct access to software solutions based on R, the Open Source version of the S-language for statistics for applied environmental statistics. For all graphics and tables presented in the book, the R-scripts are provided in the form of executable R-scripts. Statistical Data Analysis Explained: Applied Environmental Statistics with R provides, on an accompanying website, the software to undertake all the procedures discussed, and the data employed for their description in the book.
Morphometrics with R. The R language and environment offers a single platform to perform a multitude of analyses from the acquisition of data to the production of static and interactive graphs. This offers an ideal environment to analyze shape variation and shape change. This open-source language is accessible for novices and for experienced users. Adopting R gives the user and developer several advantages for performing morphometrics: evolvability, adaptability, interactivity, a single and comprehensive platform, possibility of interfacing with other languages and software, custom analyses, and graphs.
The book explains how to use R for morphometrics and provides a series of examples of codes and displays covering approaches ranging from traditional morphometrics to modern statistical shape analysis such as the analysis of landmark data, Thin Plate Splines, and Fourier analysis of outlines. The book fills two gaps: the gap between theoreticians and students by providing worked examples from the acquisition of data to analyses and hypothesis testing, and the gap between user and developers by providing and explaining codes for performing all the steps necessary for morphometrics rather than providing a manual for a given software or package.
Students and scientists interested in shape analysis can use the book as a reference for performing applied morphometrics, while prospective researchers will learn how to implement algorithms or interfacing R for new methods. In addition, adopting the R philosophy will enhance exchanges within and outside the morphometrics community.

The data sets are suitable for illustrating, among other things, the fitting of wage equations, growth regressions, hedonic regressions, dynamic regressions and time series models as well as models of labor force participation or the demand for health care.
The goal of this book is to provide a guide to R for users with a background in economics or the social sciences. Readers are assumed to have a background in basic statistics and econometrics at the undergraduate level. A large number of examples should make the book of interest to graduate students, researchers and practitioners alike. Ecological Models and Data in R. Princeton University Press, In step-by-step detail, the book teaches ecology graduate students and researchers everything they need to know in order to use maximum likelihood, information-theoretic, and Bayesian techniques to analyze their own data using the programming language R.
The book shows how to choose among and construct statistical models for data, estimate their parameters and confidence limits, and interpret the results. The book also covers statistical frameworks, the philosophy of statistical modeling, and critical mathematical functions and probability distributions. It requires no programming background--only basic calculus and statistics.
Cambridge University Press, Cambridge, Unlike other introductory books on the R system, this book emphasizes programming, including the principles that apply to most computing languages, and techniques used to develop more complex projects. The key feature of this book is that it covers models that are most commonly used in social science research-including the linear regression model, generalized linear models, hierarchical models, and multivariate regression models-and it thoroughly develops each real-data example in painstaking detail.

Focusing on standard statistical models and backed up by discussed real datasets available from the book website, it provides an operational methodology for conducting Bayesian inference, rather than focusing on its theoretical justifications.
Special attention is paid to the derivation of prior distributions in each case and specific reference solutions are given for each of the models. Similarly, computational details are worked out to lead the reader towards an effective programming of the methods given in the book. While R programs are provided on the book website and R hints are given in the computational sections of the book, The Bayesian Core requires no knowledge of the R language and it can be read and used with any other programming language.
Interactive and Dynamic Graphics for Data Analysis. Chapters include clustering, supervised classification, and working with missing values. A variety of plots and interaction methods are used in each analysis, often starting with brushing linked low-dimensional views and working up to manual manipulation of tours of several variables. The role of graphical methods is shown at each step of the analysis, not only in the early exploratory phase, but in the later stages, too, when comparing and evaluating models.
All examples are based on freely available software: GGobi for interactive graphics and R for static graphics, modeling, and programming. The printed book is augmented by a wealth of material on the web, encouraging readers follow the examples themselves. The web site has all the data and code necessary to reproduce the analyses in the book, along with movies demonstrating the examples.

It presents elementary principles of probability and statistics, which are implemented by computational tools based on the R programming language to simulate genetic experiments and evaluate statistical analyses. Each chapter contains exercises, both theoretical and computational, some routine and others that are more challenging. The R programming language is developed in the text.
The author bases his approach on a framework of penalized regression splines, and builds a well- grounded foundation through motivating chapters on linear and generalized linear models. While firmly focused on the practical aspects of GAMs, discussions include fairly full explanations of the theory underlying the methods. The treatment is rich with practical examples, and it includes an entire chapter on the analysis of real data sets using R and the author's add-on package mgcv.
Each chapter includes exercises, for which complete solutions are provided in an appendix. Numerous examples using non-trivial data illustrate solutions to problems such as evaluating pain perception experiments using magnetic resonance imaging or monitoring a nuclear test ban treaty. The book is designed to be useful as a text for graduate level students in the physical, biological and social sciences and as a graduate level text in statistics. Some parts may also serve as an undergraduate introductory course.
Theory and methodology are separated to allow presentations on different levels. Material from the earlier Prentice-Hall text Applied Statistical Time Series Analysis has been updated by adding modern developments involving categorical time sries analysis and the spectral envelope, multivariate spectral methods, long memory series, nonlinear models, longitudinal data analysis, resampling techniques, ARCH models, stochastic volatility, wavelets and Monte Carlo Markov chain integration methods. These add to a classical coverage of time series regression, univariate and multivariate ARIMA models, spectral analysis and state-space models.
The book is complemented by ofering accessibility, via the World Wide Web, to the data and an exploratory time series analysis program ASTSA for Windows that can be downloaded as Freeware.
