I hate to do this, but I would appreciate some help interpreting the attached file. I can't seem to post the image. It comes from an MIT white paper I found on fantasy football strategy.
My interpretation is I have two 32X32 (number teams) systems of the form A*x = b where, for example, b is the historical defensive statistic and each row in A represents the match ups for team k. So in the first step of the algorithm A is filled with 1's and 0's representing the matchup for that season. However, this can only be done per season, but the paper indicates the usage of historical statistics for the system. I am not sure I can use matchup information at that level as every team has faced off if you back far enough meaning A would be filled with 1's and as result, be singular. When I do it this way I end up with negative, so I don't think it is correct.
I think the subscripts are throwing me off or possible incorrect. Any feedback would be appreciated.
