Total Hockey Rating (THoR) results through end of 2013

The THoR page (http://www.statsportsconsulting.com/thor) has the latest set of Even Strength (EV)  and All (EV/PP/PK) ratings for players that appeared in over about 25 games in the past two seasons.  What is new here is that we have added a new model for EV and PP and PK to the model to our EV model.  The model for all events includes all of the terms in the EV model (see the THoR page) such as Quality of Teammates, Score Effects, and Zone Starts and adds  [...]



The Value of a Zone Start

There has been a back and forth going between Tyler Dellow of mc79hockey and David Johnson of HockeyAnalysis.com about Zone Start % (ZS%) and it’s impact on play and, in particular, the impact of ZS% on Fenwick For % (FF%) or Corsi For % (CF%).  There discussion so far is here (Dellow), here (Johnson) and here (Dellow)..   I appreciate the work of both but I prefer to think of what is gained by an individual  zone start.  Bruce McCurdy is on the right track, in  [...]



Total Hockey Rating (THoR) results through 04/14/13

The THoR page (http://www.statsportsconsulting.com/thor) has the latest set of Even Strength ratings for the top 150 players.  I’ll give some commentary below.  Since MIT Sloan, we have added rink effects for each rink to the rink effects for shots and a score effect when the score has a differential of 2 or more.  The former aims to reduce bias in recording of RTSS events while the latter is indicative of changes of style of play according to the score. We got some good feedback at  [...]



THoR takes 2nd Place in Research Paper Competition

A paper by Statistical Sports Consulting LLC co-founder Michael Schuckers and Jim Curro has won 2nd place in the Research Paper Competition at the 2013 MIT Sloan Sports Analytics Conference. Second places carries with it a $5000 prize. The conference has been called the ‘super bowl of sports analytics’.  This is the third consecutive year that Schuckers has had a paper in the finals of the competition but the first time that he has finished in the money.   Total Hockey Ratings Paper



2013 MIT Sloan Sports Analytics Conference

2013 MIT Sloan Sports Analytics Conference

We are very fortunate a paper that I wrote with a former student, Jim Curro, accepted to the MIT Sloan Sports Analytics Conference Research Paper Competition.  The paper presents a  new ratings system which we think is an improvement over the current approaches.  It creates a two-way (offense and defense combined) rating that isolates the impact of an individual player by adjusting for home ice, the quality of competition, the quality of teammates and where a player starts their shifts.  We assess the impact of a player  [...]



Going First in NHL Shootout: Postscript

A couple weeks ago I made available some work we did on the NHL shootout regarding whether there is an advantage to going first or second in the shootout.  This is a postscript to that post.Our analysis found that there was not an advantage to going first. This prompted some interest and some queries. Based on these, I’ve done some additional analysis and I want to share those. First, Bruce McCurdy of the Edmonton Journal wanted to know about whether there was a difference if the shootout  [...]



Going First in NHL Shootout: A Statistical Analysis

Going First in NHL Shootout: A Statistical Analysis

With the end of the NHL lockout and the impending return of hockey, we thought we would take another look at NHL shootouts.  (The last time around we looked at the ability of goalies and shooters and found that there was nothing but randomness.  That post is HERE.)   Our focus this time around is to look at whether or not a team goes first matters.  As most readers of this post will know, the home team has the choice of going first or second  [...]



More on NHL Faceoffs

More on NHL Faceoffs

This past Spring, two students of Schuckers did undergraduate honors theses at St. Lawrence analyzing NHL data.  Tom Pasquali who is now a graduate student in Statistics at Villanova University focused on faceoffs while another student, Jim Curro (now a graduate student in Statistics at Iowa State), did some work on player ratings.  In the NHL faceoff analysis that is linked below, we used primarily Tom’s work but also a portion of Jim’s work.  We analyzed over 200,000 faceoffs over three NHL regular seasons (2008-9,  [...]



Article on US Division I College Hockey Attendance

Article on US Division I College Hockey Attendance

Recently I got asked by the guys at WI to look at the factors that influence a college hockey teams attendance.  One of my current students at St. Lawrence knows the college hockey landscape quite well so I asked Zach Nelson to work on this project with me.   For that analysis we looked at a variety of season level metrics for all of the US Division I hockey programs over the last 10 years.  Most of those metrics focused on the things that teams  [...]



NHL Shot Probability Maps

NHL Shot Probability Maps

I recently made some league-wide shot probability maps based upon the 2009-10 NHL regular seasons.  Each map is of a particular shot type and strength of the shooting team.  The strength of the shooting team is whether they were at even strength, on the power play or were shorthanded.  The maps are limited to shots taken in the offensive zone.  Most of the methodology is the same as what is found in the DIGR paper.  I did some non-parametric smoothing using the LOESS function in  [...]
