2015-2016 correlation coefficient matrix

[Caleb Sykes]

I am continuing to develop tools to help me make a predictive model of FRC matches. Here, I compare the calculated contributions for a bunch of 2015 categories and compare them with contributions for 2016 categories.

I have attached a correlation coefficient matrix which compares week 1 2016 contributions of all 2016 non-rookies that competed in week 1 with their 2015 contributions from their last official event. I didn't bother computing some of the derived categories published in the 2016 4536 scouting database such as subtracted tower strength.

Essentially, this gives some indication of how the 2016 game tasks were related to the 2015 game tasks. Most of the correlations are positive, and the strongest correlation is often "total points" or OPR. For 2017, after we have completed week 1 events, I will probably use calculated contribution to total points to create estimated calculated contributions for all teams which did not compete in week 1.

I didn't think this effort was worth a whitepaper, but I thought I would attach it in case anyone is interested.
