Statistics 120 Statistical Computing With R. Elements are combined. • When the vectors have different lengths, the shorter vector. That many properties of statistical interest, including means, variances, and probabilities, can be expressed as expectations (or more generally, functionals of a distribution).

Thisted Languange: en Publisher by: Routledge Format Available: PDF, ePub, Mobi Total Read: 34 Total Download: 817 File Size: 46,8 Mb Description: Statistics and computing share many close relationships. Computing now permeates every aspect of statistics, from pure description to the development of statistical theory. At the same time, the computational methods used in statistical work span much of computer science. 3d Printer Design Software Ipad. Elements of Statistical Computing covers the broad usage of computing in statistics.

It provides a comprehensive account of the most important computational statistics. Included are discussions of numerical analysis, numerical integration, and smoothing. The author give special attention to floating point standards and numerical analysis; iterative methods for both linear and nonlinear equation, such as Gauss-Seidel method and successive over-relaxation; and computational methods for missing data, such as the EM algorithm. Also covered are new areas of interest, such as the Kalman filter, projection-pursuit methods, density estimation, and other computer-intensive techniques.

This book describes computationally intensive statistical methods in a unified presentation, emphasizing techniques, such as the PDF decomposition, that arise in a wide range of methods. Author by: Arkadiusz Sitek Languange: en Publisher by: CRC Press Format Available: PDF, ePub, Mobi Total Read: 36 Total Download: 377 File Size: 54,9 Mb Description: Statistical Computing in Nuclear Imaging introduces aspects of Bayesian computing in nuclear imaging.

The book provides an introduction to Bayesian statistics and concepts and is highly focused on the computational aspects of Bayesian data analysis of photon-limited data acquired in tomographic measurements. Basic statistical concepts, elements of decision theory, and counting statistics, including models of photon-limited data and Poisson approximations, are discussed in the first chapters. Monte Carlo methods and Markov chains in posterior analysis are discussed next along with an introduction to nuclear imaging and applications such as PET and SPECT.

The final chapter includes illustrative examples of statistical computing, based on Poisson-multinomial statistics. Examples include calculation of Bayes factors and risks as well as Bayesian decision making and hypothesis testing. Appendices cover probability distributions, elements of set theory, multinomial distribution of single-voxel imaging, and derivations of sampling distribution ratios. C++ code used in the final chapter is also provided. The text can be used as a textbook that provides an introduction to Bayesian statistics and advanced computing in medical imaging for physicists, mathematicians, engineers, and computer scientists.

It is also a valuable resource for a wide spectrum of practitioners of nuclear imaging data analysis, including seasoned scientists and researchers who have not been exposed to Bayesian paradigms.

The computational approach to understanding nature and technology is currently flowering in many fields such as physics, geophysics, astrophysics, chemistry, biology, and most engineering disciplines. This book is a gentle introduction to such computational methods where the techniques are explained through examples.

It is our goal to teach principles and ideas that carry over from field to field. You will learn basic methods and how to implement them.

In order to gain the most from this text, you will need prior knowledge of calculus, basic linear algebra and elementary programming. Author by: Randall L. Eubank Languange: en Publisher by: CRC Press Format Available: PDF, ePub, Mobi Total Read: 20 Total Download: 501 File Size: 43,7 Mb Description: With the advancement of statistical methodology inextricably linked to the use of computers, new methodological ideas must be translated into usable code and then numerically evaluated relative to competing procedures. In response to this, Statistical Computing in C++ and R concentrates on the writing of code rather than the development and study of numerical algorithms per se. The book discusses code development in C++ and R and the use of these symbiotic languages in unison. It emphasizes that each offers distinct features that, when used in tandem, can take code writing beyond what can be obtained from either language alone.
