Ranking Teams with Matrix Computations

[#1]

This entry contains the code from a 2008 SAS Global Forum paper, Generalizing Google’s PageRank to Rank National Football League Teams by Govan, Meyer and Albright.. The paper explores various ways to represent  the outcomes of games as a matrix and then uses a solver or an Eigen Decomposition to rank the teams. There is one IML source file attached. In the file are three different IML modules and each one performs a slightly different formulation of the "season" as a matrix and then computes a ranking. In addition to the three modules, the file contains the main IML code that drives an example. The IML modules and program are further described in the SAS Global Forum paper.
