Here is a great article on “regression toward the mean”
Although I don’t think they once mentioned that term. Anyway, this article was brought to my attention by one of our faithful readers, Eli Witus. It is about the origins of the statistical concept of regression to the mean, which is apparently called Stein’s Paradox, more or less. I had never heard of that.
What impressed me after reading the article was how inexact a science it is, in a manner of speaking, and how recently the concept was embraced (the 1950’s and 1960’s) and has evolved. I assumed that it had been around for a hundred or more years.
BTW, Eli has a very nice web site/blog for anyone interested in NBA sabermetrics (called APBRmetrics). Also, he now works for an NBA team, congratulations to him.
