You have clarified this for me by stating that it is for illustrative purposes.terpsfan101noreply@blogger.comtag:blogger.com,1999:blog-12133335.post-12320343633315036982008-10-18T10:43:00.000-04:002008-10-18T10:43:00.000-04:001) No, if I understand you correctly. The two are...1) No, if I understand you correctly. The two are unconnected--you have left your BsR equation unchanged, and applying TT will still make the usual assumptions about interaction between player and "rest of team" that it usually does.<BR/><BR/>There is no reason to use the intrinsic linear weights approach with theoretical team--if you want to use TT, just use it. The only point of the intrinsic LW for TT is to illustrate how the events are weighted in the TT process.<BR/><BR/>2) Yes, if you want to apply BsR directly to the player, you must always use TT (or some kind of differential approach). However, if you have the custom linear weights, I would just use those and go 100% linear. As illustrated elsewhere, the difference between the two approaches shouldn't be that large. It would go without saying that the straight linear approach is much cleaner. Personally, I never actually use TT BsR--it's useful as a theoretical exercise, but in practice, I consider it overkill. I just stick with linear weights for individuals.phttp://www.blogger.com/profile/18057215403741682609noreply@blogger.comtag:blogger.com,1999:blog-12133335.post-25656734224908628302008-10-18T06:43:00.000-04:002008-10-18T06:43:00.000-04:00Patriot,If I have calculated Custom LWTS on the le...Patriot,<BR/><BR/>If I have calculated Custom LWTS on the league level for each season with Baseruns, and then use the intrinsic linear weights approach for the Theoretical Team, aren't I then just using 100% Linear Baseruns? <BR/><BR/>Now, if I make new Baseruns equations for each league-season using the Custom LWTS generated from Baseruns equations that were grouped by era (i.e. AL 2001-2007), do I still need to apply the theoretical team?terpsfan101noreply@blogger.comtag:blogger.com,1999:blog-12133335.post-26432379789593333532008-07-28T13:42:00.000-04:002008-07-28T13:42:00.000-04:00Awesome, I'm glad that you are doing this--I look ...Awesome, I'm glad that you are doing this--I look forward to the next part. <BR/><BR/>I've been using linear weights for hitters in lieu of one of the other approaches simply because it's easier to do in a spreadsheet, and I figured it didn't matter that much as long as the linear weights are appropriate for the era. I suppose I could also use custom team linear weights when I'm interested in specific value to teams (e.g. my reds stat review thingies), but again, the few quick tests that I've done have indicated that it doesn't matter all that much for most players. -jJustinhttp://www.blogger.com/profile/07697776280178146413noreply@blogger.com
