I think I'll test out a few different model forms.<br /><br />Here's one issue: with linear, you assume an increase in a variable by a certain amount helps players with low PERs (11) and ones with high PERs (25, for instance.) Is this true? Will better players increase at a faster rate or a slower rate? I'll look into the issue.<br /><br />Let me know if you have any other recommendations and I'll be sure to cite you.
