Book Bayesian Model Selection and Statistical Modeling

Download or read book Bayesian Model Selection and Statistical Modeling written by Tomohiro Ando and published by CRC Press. This book was released on 2010-05-27 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Along with many practical applications, Bayesian Model Selection and Statistical Modeling presents an array of Bayesian inference and model selection procedures. It thoroughly explains the concepts, illustrates the derivations of various Bayesian model selection criteria through examples, and provides R code for implementation. The author shows how to implement a variety of Bayesian inference using R and sampling methods, such as Markov chain Monte Carlo. He covers the different types of simulation-based Bayesian model selection criteria, including the numerical calculation of Bayes factors, the Bayesian predictive information criterion, and the deviance information criterion. He also provides a theoretical basis for the analysis of these criteria. In addition, the author discusses how Bayesian model averaging can simultaneously treat both model and parameter uncertainties. Selecting and constructing the appropriate statistical model significantly affect the quality of results in decision making, forecasting, stochastic structure explorations, and other problems. Helping you choose the right Bayesian model, this book focuses on the framework for Bayesian model selection and includes practical examples of model selection criteria.

Book Discrepancy based Model Selection Criteria Using Cross Validation

Download or read book Discrepancy based Model Selection Criteria Using Cross Validation written by Simon Lee Davies and published by . This book was released on 2002 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: An important component of any linear modeling problem consists of determining an appropriate size and form of the design matrix. Improper specification may substantially impact both estimators of the model parameters and predictors of the response variable: underspecification may lead to results which are severely biased, whereas overspecification may lead to results with unnecessarily high variability. Model selection criteria provide a powerful and useful tool for choosing a suitable design matrix. Once a setting has been proposed for an experiment, data can be collected, leading to a set of competing candidate models. One may then attempt to select an appropriate model from this set using a model selection criterion. In this thesis we establish four frameworks which initialize with previously proposed model selection criteria targeting well-known traditional discrepancies, namely the Kullback-Leibler discrepancy, the Gauss discrepancy, the transformed Gauss discrepancy, and the Kullback symmetric discrepancy. These criteria are developed using the bias adjustment approach. Prior work has focused on finding approximately or exactly unbiased estimators of these discrepancies. We expand on this work to additionally show that the criteria which are exactly unbiased serve as the minimum variance unbiased estimators. In many situations, the predictive ability of a candidate model is its most important attribute. In light of our interest in this property, we also concentrate on model selection techniques based on cross validation. New cross validation model selection criteria that serve as counterparts to the standard bias adjusted forms are introduced, together with descriptions of the target discrepancies upon which they are based. We then develop model selection criteria which are minimum variance unbiased estimators of the cross validation discrepancies. Furthermore, we argue that these criteria serve as approximate minimum variance unbiased estimators of the corresponding traditional discrepancies. We propose a general framework to unify and elucidate part of our cross validation criterion development. We show that for the cross validation analogue of a traditional discrepancy, we can always find a "natural" criterion which serves as an exactly unbiased estimator. We study how the cross validation criteria compare to the standard bias adjusted criteria as selection rules in the linear regression framework. This is done by concluding our development of each of the four frameworks with simulation results which illustrate how frequently each criterion identifies the correctly specified model among a sequence of nested fitted candidate models. Our results indicate that the cross validation criteria tend to outperform their bias adjusted counterparts. We close by evaluating the performance of all the model selection criteria considered throughout our work by investigating the results of a simulation study compiled using a sample of data from the Missouri Trauma Registry.

Book Selecting Models from Data

Download or read book Selecting Models from Data written by P. Cheeseman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a selection of papers presented at the Fourth International Workshop on Artificial Intelligence and Statistics held in January 1993. These biennial workshops have succeeded in bringing together researchers from Artificial Intelligence and from Statistics to discuss problems of mutual interest. The exchange has broadened research in both fields and has strongly encour aged interdisciplinary work. The theme ofthe 1993 AI and Statistics workshop was: "Selecting Models from Data". The papers in this volume attest to the diversity of approaches to model selection and to the ubiquity of the problem. Both statistics and artificial intelligence have independently developed approaches to model selection and the corresponding algorithms to implement them. But as these papers make clear, there is a high degree of overlap between the different approaches. In particular, there is agreement that the fundamental problem is the avoidence of "overfitting"-Le., where a model fits the given data very closely, but is a poor predictor for new data; in other words, the model has partly fitted the "noise" in the original data.
