Performance Index Rating (PIR) is a basketball mathematical statistical formula that is used by the Euroleague Basketball Company's first and second tier competitions, the EuroLeague and the EuroCup, as well as various European national domestic and regional leagues. It is a part of the Tendex basketball rating system. It is also variously ...
Sports ratings systems use a variety of methods for rating teams, but the most prevalent method is called a power rating. The power rating of a team is a calculation of the team's strength relative to other teams in the same league or division. The basic idea is to maximize the number of transitive relations in a given data set due to game ...
The Wilks coefficient or Wilks formula is a mathematical coefficient that can be used to measure the relative strengths of powerlifters despite the different weight classes of the lifters. Robert Wilks, CEO of Powerlifting Australia , is the author of the formula.
The Tendex system is a basketball mathematical statistical formula that was created by sports writer Dave Heeren, [1] in order to determine the playing efficiency of basketball players. [ 2 ] [ 3 ] [ 4 ] It is generally accepted as the original weighted advanced stat formula used in the sport of basketball.

The formula was adjusted in 2007 to account for games against FCS teams. [ 4 ] Colley Matrix is a special case of the Generalized row sum method, a parametric family of ranking methods developed by P. Yu. Chebotarev (1989).
He re-ranked all past seasons with this new formula; these new champions were printed in the 2000 [13] –2003 [14] NCAA records books. Prior to the 2001 season, Billingsley again changed the formula in order to remove "Margin of Victory" from the system's BCS calculations. This third set of champions appeared in the 2004 [15] –2012 [16] NCAA ...
This definition of Guttman scale relies on the prior definition of a simple function. For a totally ordered set X , say, 1,2,..., m , and another finite set, Y , with k elements k ≤ m , a function from X to Y is a simple function if X can be partitioned into k intervals which are in a one-to-one correspondence with the values of Y .
