What is PECOTA? Here’s some info from Baseball Prospectus.
(PECOTA) Stands for Player Empirical Comparison and Optimization Test Algorithm. PECOTA is BP’s proprietary system that projects player performance based on comparison with historical player-seasons. There are three elements to PECOTA:
1) Major-league equivalencies, to allow us to use minor-league stats to project how a player will perform in the majors;
2) Baseline forecasts, which use weighted averages and regression to the mean to produce an estimate of a player’s true talent level;
3) A career-path adjustment, which incorporates information about how comparable players’ stats changed over time.
