Although, when I think about it, it seems that getting a counterintuitive result is more likely because when a team is up after the eigth, they don't bat in the ninth, meaning 11% less runs ABs on average in a win. With that in mind, it makes some sense - whatever advantage is afforded by having a beneficial home park is negated by losing that extra frame.<BR/><BR/>Stats... <BR/><BR/>I hope you enjoy getting your formal training - you seem to be the kind of person who will find it interesting.Kiffyhttp://www.blogger.com/profile/05248584571583250293noreply@blogger.comtag:blogger.com,1999:blog-33122630.post-12399043929372787102007-02-12T12:34:00.000-05:002007-02-12T12:34:00.000-05:00That is an excellent point. Using my data I found that the Standard Deviation of runs scored and runs/game is 0.71, which is quite high. That's interesting, because while Runs/Game are well correlated with wins (duh), standard deviation is not. <BR/> <BR/>As for your other point, I went to ESPN.com and found the park factors for all 30 stadiums in 2006. Based off of this, the correlation between a team's home park factor and its runs scored per game is -0.09. The correlation between park factor and standard deviation of runs scored is even less, at r = 0.02. So while the Rockies have a hitters' park and a high deviation, they do not appear to be indicative of a trend.<BR/> <BR/>Thanks for your comments.mehmattskihttp://www.blogger.com/profile/17746570756439422280noreply@blogger.comtag:blogger.com,1999:blog-33122630.post-81362057360961461572007-02-12T00:48:00.000-05:002007-02-12T00:48:00.000-05:00The more runs a team scores, the greater the standard deviation. This is the largest single reason for the Yankees having such a large standard deviation.<BR/><BR/>Second, the greater the advantage/disadvantage afforded in scoring runs by a team's home ballpark, the greater the standard deviation. Look at the Rockies. I like the concept, but think you've drawn conclusions that aren't necessarily true.Kiffyhttp://www.blogger.com/profile/05248584571583250293noreply@blogger.com
