When the predictors are more elaborate, and especially when the predictors are metric, this situation is referred to as “logistic regression” because of the logistic (inverse) link function. Bayesian inference is a method of statistical inference in which Bayes' theorem is used to update the probability for a hypothesis as more evidence or information becomes available. Bayesian inference is an important technique in statistics, and especially in mathematical statistics. Bayesian updating is particularly important in the dynamic analysis of a sequence of data.
