Rioja or Ribera? Frequentist vs Bayesian statistics.

Abstract

Frequentist statistics, the best known and to which we are most accustomed, is the one that is developed according to the classic concepts of probability and hypothesis testing. For its part, Bayesian statistics incorporates external information into the study that is being carried out, so that the probability of a certain event can be modified by the previous information that we have on the event in question. We review some of the arguments against the frequentist approach, which are based on a misuse of its methodology rather than on the method's own weaknesses.
