A hands-on introduction to computational statistics from a Bayesian point of view§§Providing a solid grounding in statistics while uniquely covering the topics from a Bayesian perspective, Understanding Computational Bayesian Statistics successfully guides readers through this new, cutting-edge approach where inferences are based on random samples drawn from the posterior distribution. With its hands-on approach, step approach, the book shows readers how samples can be drawn from the posterior distribution when the formula giving its shape is all that is known, and how Bayesian inferences can be based on these samples from the posterior. These ideas are illustrated on common statistical models including the multiple linear regression model, the hierarchical mean model, the logistic regression model, and the proportional hazards model.§§The book begins with an outline of the similarities and differences between Bayesian and the likelihood approaches to statistics. Subsequent chapters present key techniques for using computer software to draw Monte Carlo samples from the incompletely known posterior distribution and performing the Bayesian inference calculated from these samples. Topics of coverage include:§ Direct ways to draw a random sample from the posterior by reshaping a random sample drawn from an easily sampled starting distribution§ The distributions from the one-dimensional exponential family§ Markov chains and their long-run behavior§ The Metropolis-Hastings algorithm§ Gibbs sampling algorithm and methods for speeding up convergence§ Markov Chain Monte Carlo Sampling§§Using numerous graphs and diagrams, the author emphasizes a step-by step approach to computational Bayesian statistics. At each step, important aspects of application are detailed, such as how to choose a prior for logistic regression model, the Poisson regression model, and the proportional hazards model. A related web site houses R functions and Minitab(r) macros for Bayesian analysis and Monte Carlo simulations, and detailed appendices in the book guide readers through the use of these software packages.§§Understanding Computational Bayesian Statistics is an excellent book for courses on computational statistics at the upper-level undergraduate and graduate levels. It is also a valuable reference for researchers and practitioners who use computer programs to work with data and solve problems in their everyday work.Bayesian statistics allows the use of assumptions to eliminate improbable paths. The Bayesian view has many important theoretical aspects that students should be familiar with if they are going into fields where statistics will be used. This book uniquely covers the topics usually found in a typical introductory statistics book but from a Bayesian perspective.A hands-on introduction to computational statistics from a Bayesian point of view§§Providing a solid grounding in statistics while uniquely covering the topics from a Bayesian perspective, Understanding Computational Bayesian Statistics successfully guides readers through this new, cutting-edge approach where inferences are based on random samples drawn from the posterior distribution.
