摘要

Over the course of the past two articles (Part 44, Oct 2011, and Part 45, Nov/Dec 2011), R~2 has been defined, its components have been explained verbally and mathematically, and the statistic's formula has been presented. Also included has been a discussion of the limitations of R2, and the traps that lie in wait for those who rely exclusively or too heavily on this number. Is there a way to cast this often-used statistic in a more favorable light? This installment will address that question, as well as offer a more robust path for evaluating candidate models.
