When are Bayesian methods preferable to Frequentist?
a mathematical recipe for going from what we already know (the prior) to what we should believe next (the posterior), based on what we are learning now (the likelihood).
Bayes’s rule as a way to update our belief in a particular hypothesis.
The point of Bayesian decision theory is to help make a decision. Or, more accurately, to describe the optimal way of making a decision, given uncertainty about the outcome.
