WebBayesian probability is the study of subjective probabilities or belief in an outcome, compared to the frequentist approach where probabilities are based purely on the past occurrence of the event. A Bayesian Network captures the joint probabilities of the events represented by the model. The interpretation of Bayes' rule depends on the interpretation of probability ascribed to the terms. The two main interpretations are described below. Figure 2 shows a geometric visualization. In the Bayesian (or epistemological) interpretation, probability measures a "degree of belief". Bayes' theorem links the degree of belief in a proposition b…

"WebThe Bayesian approach to data analysis differs from the frequentist one in that each parameter of the model is considered as a random variable (contrary to the frequentist approach which considers parameter values as unknown and fixed quantities), and by the explicit use of probability to model the uncertainty (Gelman et al., 2013).
