Chapter 7
Chapter 7 is US liquidation bankruptcy — a trustee sells assets and pays claims in priority; the going concern is over.
Bayesian Inference
Bayesian inference updates a prior distribution over parameters with data via Bayes’ rule to get a posterior — beliefs as probabilities, not just a point estimate.
Entropy
Shannon entropy H(P) = −Σ p log p is the expected surprise of a distribution — a measure of uncertainty used in information theory, portfolio tilts, and some max-ent priors.
12-Month Cycle in the Cross-Section of Stock Returns
Use same-calendar-month returns in prior years as a cross-sectional signal — annual seasonality in the stock sort.
