Bayesian statistics is a system for describing epistemological uncertainty using the mathematical language of probability. In the Bayesian paradigm, degrees of belief in states of nature are specified; these are non-negative, and the total belief in all states of nature is fixed to be one. Bayesian statistical methods start with existing prior beliefs, and update these using data to give posterior beliefs, which may be used as the basis for inferential decisions.
