WebJun 20, 2016 · An important part of bayesian inference is the establishment of parameters and models. Models are the mathematical formulation of observed events. Parameters are the factors in the models affecting the observed data. For example, in tossing a coin, the fairness of the coin may be defined as the parameter of the coin denoted by θ. Bayesian statistics is a theory in the field of statistics based on the Bayesian interpretation of probability where probability expresses a degree of belief in an event. The degree of belief may be based on prior knowledge about the event, such as the results of previous experiments, or on personal beliefs about the event. This differs from a number of other interpretations of probability, such as the frequentist interpretation that views probability as the limit of the relative frequency of …
