Bayesian Models for Categorical Data
using Bayesian tools for the research of knowledge has grown considerably in components as different as utilized facts, psychology, economics and clinical technology. Bayesian equipment for express facts units out to demystify sleek Bayesian equipment, making them obtainable to scholars and researchers alike. Emphasizing using statistical computing and utilized facts research, this booklet offers a complete creation to Bayesian equipment of specific outcomes.
* stories contemporary Bayesian method for specific results (binary, count number and multinomial data).
* Considers lacking info types ideas and non-standard versions (ZIP and damaging binomial).
* Evaluates time sequence and spatio-temporal versions for discrete data.
* gains dialogue of univariate and multivariate techniques.
* offers a collection of downloadable labored examples with documented WinBUGS code, to be had from an ftp site.
The author's earlier 2 bestselling titles supplied a accomplished creation to the speculation and alertness of Bayesian versions. Bayesian types for specific information maintains to construct upon this origin via constructing their software to specific, or discrete information - the most universal varieties of info to be had. The author's transparent and logical method makes the publication obtainable to a variety of scholars and practitioners, together with these facing express facts in medication, sociology, psychology and epidemiology.
