| Popis: | A recent article by Huberty (1994) discusses significance testing of R(2) in linear regression and the definition of a corresponding effect size index. It recommends an adjustment to the standard null hypothesis, p(2) = 0, in order to adjust for an upward bias in the statistic R(2). This note suggests that the adjustment proposed by Huberty has some conceptual shortcomings. Existing improvements on R(2) are described in some detail. |
