NHLErrata launch

Ever since I started collecting the NHL data it was very important to me to validate the collected information. So I created a set of checks that finally formed a whole library to test both the NHL boxscore feeds and the HTML reports. I managed to fish out quite a few errors and inconsistencies. Some where systemic, and could be fixed in software, some required a manual intervention, sometimes by editing the source file, sometimes by providing the correct value overriding what the parser woul

Website A Page - A Day, Part VI - Warm Welcome   Original post Prologue Part I Part II Part III Part IV Part V With nothing else to do for about half an hour, why not to resume the series?

A Lemma Research - Penalty Box and TOI - Part II

Original post.   Part I   After completing the first part of the lemma research - penalty box - the second part was shorter, easier, but just as useful. I decided to find out the share of time teams spend on average while at even strength, on power play/shorthanded and with empty net. Then given this number, and the number of goals scored in each such situation, I was able to calculate the frequency of EVG/PPG/SHG/ENG or the reverse of it which I called the difficult of such g

A Lemma Research - Penalty Box and TOI

Original post   Nothing derails from the regular blogging like a research that you've been so eager to start, but were putting off to finish simpler and more materialistic stuff, but then you couldn't hold it off any longer.But then, I realized that in order to do that research I need to perform a lemma research. Just like its mathematical namesake, a lemma research is one that is done for the sake of a bigger one, yet producing a useful result by itself.So I noticed that I needed the

A suggestion for the All-Star Game

Original post.   While the series "Website - A Page A Day" is being delayed by all kinds of things, here comes a short post on a different topic. Last year, in my opinion, the accuracy shooting competition which included shooting the pack from the goal line into a small hole was, in my opinion a total failure. Mike Smith's spectacular score across the rink did the injustice and provided a false impression this skill contest was any good. Otherwise, the competition was not exciting t

The Website - A Page A Day - Prologue

Original Post   Hello, hockeyforums.net, from Mr. Van Winkle...This prolonged silence was caused by a lot of factors, led, naturally, by REAL LIFE™. But I also made a fundamental mistake in the infrastructure setup, and so I had to roll out a hastily patched setup when the season was starting; I then went back and worked on this infrastructure fix, the work which continued over three months and is now complete! Unfortunately, all this work will not be visible to the visitor, with possi

On carrying Momentum...

Original post.   Frequently, the importance of carrying momentum over an intermission can be heard being talked about. I thought it were possible to measure this harmony with algebra, so I tried to do that. I choose to analyze a very specific question: If the regulation of a game ends in a tie, other than 0-0, how frequently would the team that tied the game with the last regulation goal win in overtime. We would define the team that tied the game as the one having the momentum. We wou

On the NHL Scoring System - Part III

It looks like I've forgotten to translate a couple of entries. Correcting that.   Original post.   Part IPart IIOnce again, driven by idea that if you want to encourage goal scoring, you need to reward the goal scoring in standings directly, not indirectly through winning. Then, based on the idea of a fellow hockey fan and blogger, a new suggestion was born in my mind.Not so long ago I was involved in another discussion on the subject on Twitter, where an interesting alt

On Buchholz and Sonneborn-Berger coefficients - Part II

Original post. 2. The Sonneborn-Berger coefficient.This stranger beast is a metric extensively used for tie-breaks in chess-round robins and as an auxiliary tie-break tool to the Buchholz coefficient in non-round robins. Let's start with the definition.   SB = Σn=1N f(Rn,Pn)   where Rn is the result against the n-th opponent, and Pn is the opponent's points score.The function  f(Rn, Pn) is defined as:f(Win, Pn)  = Pnf(Tie, Pn)  = Pn/2f(Loss, Pn) = 0The result value evaluates w

On Buchholz and Sonneborn-Berger coefficients

Original post.   The practice of chess tournaments provides two traditional metrics that are used to rank participants beyond their mere scoring. Their names are the Buchholz coefficient and the Sonneborn-Berger coefficient (often called just Berger). They are frequently used as tie-breakers in chess events, however I arrived to completely different application for them for the National Hockey League seasons.1. The Buchholz coefficientThe Buchholz coefficient is simply the sum of the p

Faceoff statistics

I read about this idea on HFBoards and finally got to implement it.   Faceoff stats and Elo ratings.   The available views are: * career/specific season * per zone/per stick first   Here's a sample table: By stick first on the ice, 2016 season. FW - First Stick Wins, FL - First Stick Losses, FP - First Stick Win % LW - Last Stick Wins, LL - Last Stick Losses, LP - Last Stick Win % TW - Total Faceoff Wins, TL - Total Faceoff Losses, TP - Tota

Another rule change suggestion

Original post.   Better less, but better V.I. Lenin I've got another rule change suggestion, this one even simpler:Allow teams to decline penalty shot awards in favor of a regular power-play.I think it adds more tactical variety to the game and discourages penalties on breakaways that are worse in penalty shooting.As a side matter, I think: a player who is charged with the offense after which the penalty shot is awarded should still be added a minor penalty (2 minutes) in the s

On goalposts statistics

Why does the cat lick his balls? Because it can.   Recently I saw a request on a stats of goal posts / crossbars hit per game. While I do have that statistic per player, I haven't one for games, so - since I can - why shouldn't I produce one? About half an hour of Perl-ing created the following summary:   Irons altogether, top: AWAY    HOME                P C T OTT  vs BUF  on 2011/12/31: 8 0 8 VAN  vs FLA  on 2010/02/11: 7 0 7

On streaks and breaks

Original post.   So after remembering the Botwinnik's quote, and after publishing the stats how the teams actually play after different breaks, a new idea came to me - check whether the teams on streaks are affected positively or negatively by breaks.For the sake of the analysis, I assumed the following: A break is a period of three days at least between games. A streak is a sequence of at least three wins in a row, or at least seven points in four games. So we check

A rule change suggestion

whoops, got the title wrong Original post. A rule change suggestion   There's no irreplaceable people. I.V. Stalin   Rushing this one up, because this idea already came to my mind before, but I forgot about it. The age is taking its toll. Anyways. Everyone is talking these days about rule changes. I've already expressed a few thoughts on the scoring systems, but I am not original there. Now, however, I want to make a suggestion I haven'

On A Hockey Website

Original post.   Just to not let the month of January slip away without another post, I got sentimental and decided to tell a small story about how my website came to life.There was a void. A lot of time people on hockey boards would wonder if specific statistics of players and teams were available, and they wouldn't, although the raw data seemed to be there. Then, there was the fantasy hockey world, with its pizzazz, and asking for a predictive tool, - and again, the raw data seemed t

On Intangibles (a small addendum)

Original post.   One "intangible" being tossed around is "motivation" of the players. Which brings memories of an episode I was witness to.   In 2003/04, in the Israeli Top Tier Chess League (which is indeed no slouch) our club managed to assemble an outstanding team, featuring, among others, a former Champion of Russia and a former Champion of Europe. I was part of the management team, and orchestrated bringing the first of the two, who also happened to be my childhood frien
