Rating Trends

October 11, 2016

The virtual ink wasn't dry on Ratings Trends before the obvious extension to performing the same analysis for every rating that I'd done for the Majority Consensus came to mind. It takes a few minutes on a six year-old computer but it's worth it because as a byproduct there's a convenient report of team rank trends for each of the ratings Dr. Massey includes in his summary. In that report the team name links to the schedule page that includes team and opponents' Majority Consensus ranks.

Presenting the temporal correlations for 100+ ratings is something of a challenge. My first cut included all ratings in one very large (about 6MB) file with an index at the top that just shows the weeks for which I have data.I changed it to reference one page per ranking, which is slower to upload, but much faster to download (you're welcome.)

The alternate index pesents the distance between successive rankings for each rating.

The measure of week-to-week variance listed in the reports is the distance between week N and week N+1. This is defined as the total number of team-pair swaps it takes to turn one ranking into the other.
