In other words, when subtracting a run, as you stated, you're not subtracting a run from a specific game, allowing a possible change from a zero run game to a -1 run game. You're subtracting 1 run from a 721 run average 2018 major league season, and redistributing those 720 runs in a new gammma distribution with a slightly smaller mean, and variance probably still a multiple of about 1.1 times the mean.<br /><br />https://stats.seandolinar.com/mlb-run-distribution-neg-binomial/<br /><br />I'm sure such results would be a shade less "extreme" than removing a specific run from a specific game.<br /><br />I don't disagree with your point about reducing opponents runs being more effective for a better than average team, increasing your own run production being more effective for a worse than average team.<br />Unknownhttps://www.blogger.com/profile/15999469754997104765noreply@blogger.comtag:blogger.com,1999:blog-31545676.post-69902485669379420452018-12-04T12:35:23.320-05:002018-12-04T12:35:23.320-05:00Of course.

Of course, you then need to sample from runs if you are subtracting (or run opportunities if you are adding) rather than games. I should have gotten that. :)Scott Segrinhttps://www.blogger.com/profile/17707976016425293072noreply@blogger.comtag:blogger.com,1999:blog-31545676.post-33075995510534521672018-12-03T22:37:23.126-05:002018-12-03T22:37:23.126-05:00I understand the argument/conclusion from simply a...I understand the argument/conclusion from simply a "counting stat".<br />I was too focused on the "how's".Unknownhttps://www.blogger.com/profile/08881822855187378673noreply@blogger.comtag:blogger.com,1999:blog-31545676.post-52751619463226830932018-12-03T16:37:21.287-05:002018-12-03T16:37:21.287-05:00A much simpler way to say it: runs are a counting ...A much simpler way to say it: runs are a counting stat. It makes no sense to adjust in whole increments a counting stat within an individual game, where this stat might not even occur once.Anonymousnoreply@blogger.com
