Question
What is the purpose of Bayesian analysis?
Solution
Bayesian analysis is a statistical procedure which is used to update the probability for a hypothesis as more evidence or information becomes available. It's named after Thomas Bayes, who proved a special case of what is now known as Bayes' theorem.
Here are the steps to understand the purpose of Bayesian analysis:
-
Prior Knowledge: Bayesian analysis starts with existing "prior" beliefs, or knowledge, about the probability of an event. This prior knowledge is not fixed and can be updated as new data comes in.
-
New Data: As new data or evidence becomes available, Bayesian analysis updates or revises the prior beliefs. This is done using Bayes' theorem,
