WebBayesian analysis is a statistical method that makes inference on unknown quantities of interest (which could be param- eters in a model, missing data, or predictions) by combining prior beliefs about the quantities of interest and information (or evidence) contained in an observed set of data. WebN2 - Standard methods for analyzing binomial regression data rely on asymptotic inferences. Bayesian methods can be performed using simple computations, and they apply for any sample size. We provide a relatively complete discussion of Bayesian inferences for binomial regression with emphasis on inferences for the probability of “success.”
