All but one of the ranking systems on this page come from the College Hockey Ranking Systems page of slack.net/hockey and are described in more detail there.

Record
A team's winning percentage (Pct) is calculating dividing its games won by its games played.
RPI
The Ratings Percentage Index, is a linear combination of a team's winning percentage with the winning percentages of its opponents and its opponents' opponents. The column labelled "Hockey RPI" weights these three contributions 35%, 50%, and 15%, respectively, which is the weighting used in college hockey. The column labelled "NCAA RPI" uses the NCAA's original 25%:50%:25% weighting, which is as far as we know the weighting used in lacrosse. The rating is further broken down on our RPI page.
KRACH
Ken's Rating for American College Hockey is an application of the Bradley-Terry method to college hockey (so in principle this column should be labelled "Bradley-Terry" in the lacrosse table, but we're lazy); a team's rating is meant to indicate its relative strength on a multiplicative scale, so that the ratio of two teams' ratings gives the odds of each of them winning a game between them. The ratings are chosen so that the expected winning percentage for each team based on its schedule is equal to its actual winning percentage. The Round-Robin Winning Percentage (RRWP) is the winning percentage a team would be expected to accumulate if they played each other team an equal number of times. More information can be found on our KRACH page.
PWR
The PairWise Rating is determined by performing PairWise Comparisons (PWC) according to the NCAA's hockey selection criteria between all teams with winning percentages at or above .500 and totalling the number of comparisons each team wins. More information, including a breakdown of comparisons won and lost according to criteria, can be found on our PWC/PWR page. (Note that this is not the method used to select and seed the lacrosse tournament field. This page was put together in response to a question on how the hockey criteria would look applied to lacrosse.
KPWR
The KRACH-modified PairWise Rating is analogous to the PWR, except that comparisons are performed using a modified set of criteria which use the KRACH ratings to take into consideration the strength of a team's opponents. More information, including a breakdown of comparisons won and lost according to criteria, can be found on our KPWC/KPWR page.
