The Formal Theorem

P(H|D) \propto P(D|H)P(H)

Analytical Intuition.

Bayesianism is the Geometry of Updated Belief. Starting with a 'Prior' (what you knew) and updating it with new data to get a 'Posterior.' Probability as a measure of certainty, not just frequency.

CAUTION

Institutional Warning.

The Prior is subjective, which was controversial. But it allows math to incorporate experience and intuition.

Academic Inquiries.

What is a Conjugate Prior?

A prior that results in a posterior of the same family, making the math beautiful and easy.
