Monday morning statgeek: An early look at volatility

We aren't as close to having Gabriel Desjardins analyze player trends and bring expert predictive analysis to Hockey Night in Canada, but for what it's worth, Ron MacLean wore a suit on Saturday that looks a bit like the one Sheldon Cooper sometimes wears in The Big Bang Theory.

Volatility, loosely explained, is the calculation of how many goals a player will be on the ice for in a 60-minute timespan, both for and against, powerplay and shorthanded. The idea is that your players with higher volatility are unpredictable and more can happen when they're on the ice.

Seeing as its so time-consuming and there's no guarantee that it will offer me any insight into player trends because it turns out goals are a completely random occurence, I'm only taking into account players for Canadian teams in these statistics.

Notably high players:

Mathieu Darche - 8.7 MIN played, 1 GF, 1 GA, 13.79 VOL
Zack Storini, 9.1 MIN played, 1 GF, 1 GA, 13.19 VOL
Nikolai Kulemin, 30.5 MIN played, 3 GF, 3 GA, 11.80 VOL
Mike Komisarek, 25.9 MIN played, 3 GF, 2 GA, 11.58 VOL
Mikael Grabovski, 31.5 MIN played, 3 GF, 2 GA, 3.52 VOL

Notably low players:

With several players at 0, it's best to note that Dan Hamhuis has played the most minutes without having been on the ice for a goal. The player who has played the most minutes without having surrendered a goal is Tomas Kaberle. The high forward is Tyler Bozak.

The other thing I get looking closer into the plus/minus stat is to determine goals for per minute and goals against per minute.

High goals for ratio:

Mike Cammaleri: 7.10 GF/60
Jim Vandermeer: 7.06 GF/60
Mike Komisarek: 9.95 GF/60

High goals against ratio:

Chris Phillips: 7.46 GA/60
Raitis Ivanans: 7.23 GA/60
Tanner Glass: 7.06 GA/60

These are early numbers, so take them with a grain of salt. Is Mike Komisarek not a steady stay-at-home defenseman? Should Ron Wilson skate Nikolai Kulemin instead of Phil Kessel as an extra-attacker? Is Raitis Ivanans better at blocking punches with his face than he is blocking shots? Will I get laid this month?

Statistically speaking, the sample size isn't high enough to generate a sure answer for all but one of those questions, but Monday morning statgeek will take a look at volatility ratings bi-weekly (the one that means once every two weeks, not the one that means twice a week).

Vancouver host Florida and Ottawa are in Washington tonight. Ottawa has two goals in two games, so if you were lucky enough to pick up Michael Neuvirth in your pool, today would be a good day to start him.

    Not sure if you're breaking out the PP and SH minutes, but your really need to if you're going to look at this. They will very significantly alter any conclusions. As to your other (rhetorical) questions ...

    Is Mike Komisarek not a steady stay-at-home defenseman?
    Who cares?


    Should Ron Wilson skate Nikolai Kulemin instead of Phil Kessel as an extra-attacker?
    No, he should use Taylor Hall. Oh.


    Is Raitis Ivanans better at blocking punches with his face than he is blocking shots?
    He needs some positive stat to work with, after all.


    Will I get laid this month?
    The good news is, the SC just tossed a lot of the anti-prostitution laws.

  2. I have started breaking down PP and SH minutes. I'll end up with an overall, an EV, a PP and an SH plus and minus statistic for each player on a Canadian team.
