How are HockeyAnalysis ratings (HARO, HARD, HART) calculated?

Every now and again someone asks me how I calculate HARO, HARD and HART ratings that you can find on stats.hockeyanalysis.com and it is at that point I realize that I don’t have an up to date description of how they are calculated so today I endeavor to write one. First, let me define HARO, HARD and HART. HARO – Hockey Analysis Rating Offense HARD – Hockey Analysis Rating Defense HART – Hockey Analysis Rating…

Now with charts…

I have a ton of information on my stats website stats.hockeyanalysis.com but one of the things I have always wanted to do is to make it more visual and I’d like to announce the first step in that process.  Thanks to google and their cool google chart api I have now added bubble charts when you do a stats search that returns no more than 30 players (more than 30…

What is Rick Nash?

So word has come out over the last day that Rick Nash is, at least on some level, available in a trade from the Blue Jackets.  So, the question is, who is Rick Nash and would you want him on your team?

Players Worth by Position – Revised

I wrote an article a few weeks ago about the offensive and defensive contribution (i.e. their HARO+ or HARD+ rating multiplied by ice time) of each position (C, LW, RW, D and G) but I have come to realize that my methodology is incorrect and thus the conclusions are incorrect (at least when looking at league-wide results).  The reason is, in my rating system contribution is evenly distributed among the…

The Career Progression of Grabovski-Kulemin-MacArthur Line

The best and most consistent line for the Maple Leafs this past season was the Grabovski-Kulemin-MacArthur line.  This trio of forwards are all just entering their primes at ages 27, 24 and 26 respectively and they were the second, third and fourth leading point producers on the Leafs.  I thought it might be interesting to take a look at how these three guys careers have progressed up to now.  Here…

Introducing New Stats Site

I have been pretty quiet here recently not because of a lack of things I want to write about but because I needed to get my stats site up and running first so I can reference it in my writings.  Plus, getting my stats site up has been on my todo list for a real long time.  There will be a lot more stats to come including my with/against on…

Player Evaluation Model Improvements

On Monday I outlined an all-encompassing player evaluation model that allows us to evaluate every forward, defenseman and goalie under the same methodology.  In short, the system compares how many goals are scored for and against while a player is on the ice and compares it to how many goals scored for/against one should expect based on the quality of his line mates and opposition.  That model, I believe, makes…
