LRMC is a college basketball ranking system designed to use only basic scoreboard data: which two teams played, whose court they played on, and what the margin of victory was.
LRMC stands for "Logistic Regression/Markov Chain", the two primary mathematical techniques that were a part of our system. We've subsequently added a Bayesian component as well.
We calculate two types of LRMC rankings:
- Standard (Bayesian) LRMC rankings -- These are our most-accurate LRMC rankings, which use full information about home court advantage and margin of victory.
- LRMC(0) -- Since the NCAA prefers to de-emphasize margin of victory so teams aren't encouraged to run up the score and players don't get focused on point spreads, we calculate a version of LRMC for them that doesn't take margin of victory into account. These LRMC(0) rankings are less accurate than standard LRMC, but they're compatible with NCAA's mission and preferences.
