Why This Matters

Uncertainty Is the Language of Modern Decision-Making

Every serious analytical organization — from the FDA to Goldman Sachs to MLB front offices — requires probabilistic reasoning. Point estimates are not enough. If you cannot quantify uncertainty, you cannot sit at the table where decisions get made.

Stan Is the Gold Standard — and Hiring Managers Know It

Stan powers production models at Amazon, J&J, Pfizer, and every major sports front office. It is explicitly listed in job postings for senior data scientist roles at $120K to $200K+. Learning Stan is not optional if you want to work at the highest levels.

Why This Matters

Real Data Is Messy. These Models Handle It.

Overdispersion, zero-inflation, and complex ranking structures show up in every real dataset. Pharma trials have excess zeros. Sports data has overdispersed counts. Player rankings need principled comparison. This phase gives you what basic models cannot.
