Frequentist vs. bayesian statistics
WebWhy frequentist vs Bayesian? Bayesian analysis requires a well-formed prior; which either requires additional work from users who are often not trained to form those priors or an automated approach that has a bias to a lack of change and can give slower results than the frequentist approach.

Webt. e. 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.
