Most baseball fans are familiar with the concept of ‘normalizing’ statistics. For MLB statistics, the most basic adjustment is to normalize for park effects. The simplest park normalization calculation takes the impact of a team’s park on runs scored then divides that number, either positive or negative, in half, and then that calculation is applied […]

Tom M. Tango at the The Book Blog is requesting fans to fill out playing time estimates for the team they follow closely.   In the past, these fan generated playing time forecasts have proven to be better than the ‘expert’ forecasts and better than ‘automated’ forecast systems.

Major League Equivalents (MLEs) are a series of calculations designed to take non-major league baseball performance and estimate what that performance’s results would look like statistically in the context of the Major Leagues.

I never like to assume, so once again a quick clarification from the previous segment: In Step #4, Leagues Park Difference, the 13% Park Difference will expand or contract depending on the SPECIFIC parks a player is coming from and going to.

Before moving on to Part III, there’s a clarification I need to make regarding Part II. In addition to factoring in the difference in league parks between any two leagues when doing MLE’s, you must also factor in the difference between league SCORING environments. In the previous Part II, I ‘plugged’ a 7% difference into […]
