The Methodology of this Book is Seriously Flawed
This Book attempts to Normalize baseball statistics for all players since 1901 across time for the period 1996-2001. Unfortunately, the statistitical methodology is seriously flawed. What Thomas does is to seek out the performance in each season relative to other performers in that season, and then normalize it by straight multiplication by the 1996-2001 norms without holding outs firm. You can't do that because if you increase the humber of home runs and doubles and triples etc. there's still 27 outs per team, per game; you have to normalize the stats while holding the outs the same. For this reason, the Runs Created method of Bill James is superior, because it normalizes statistics across each era while holding outs frozen, plus it adequately accounts for the defensive contribution of each player's glove, which thomas seems totally to ignore.Was this review helpful?
