A look at the US Olympic Squad for Sochi from Analytics perspective

So I’ve been in Helsinki this Autumn and as a result haven’t gotten to see much live NHL hockey.  (I’ve seen plenty of pee wee and bantam hockey as well as a couple of SM Liiga matches.)  We’re headed home just after the end of the year and one of the highlights once we get back to the states will be watching the Olympic hockey tournament.  Should be a blast.  To that end, I thought I would take a look at the candidates for the  […]



THoR for ALL

We are excited to present the first results for the Total Hockey Rating model for all events.  Our new model uses much of the same structure found in the original even strength version of THoR but we have added additional terms to account for the additional variability and values.  Here is a link to the original THoR paper as well as to our recent case for why even strength THoR is a very strong measure of player performance.  We have improved on that with this  […]



The Case for THoR

This past February we introduced the Total Hockey Ratings or THoR at the MIT Sloan Sports Analytics Conference where it won 2nd place in the research paper competition.  THoR rates players by taking the probabilities of a subsequent goal for every event for which they are on the ice and accounting for who they played with, who they played against, where their shift started, the score of the game as well as whether or not they were at home.  In doing so we isolate the two-way impact  […]



An Evaluation of the Total Hockey Rating (THoR), Part III

This is the third part of a series that looks in more depth at the Total Hockey Ratings that we developed.  In Part I, I looked at the year to year correlations for THoR,  Gabe Desjardins’ Corsi Rel and  (HART) .  Part II discussed the validity, or the relationship between the response in the THoR model, NP20, and winning.  In this part, we’re going to take a look at some individual players through the lens of THoR.  We’ll look at some players that have come to be associated  […]
