Statistical Methods Direct

While traditional (frequentist) statistics treat parameters as fixed unknowns, treat them as random variables with prior distributions. Bayes' Theorem updates the probability of a hypothesis as new evidence arrives. This approach is incredibly powerful in machine learning (Naive Bayes classifiers), A/B testing, and risk assessment because it incorporates prior knowledge explicitly.
