Darhub.dat
Darhub is a SAS data step program that calculates Darlington’s (1990) F statistic for testing the significance of difference between the obtained squared multiple correlation coefficient, R2, and the expected value, or expected long-run mean, of R2 under the null hypothesis that ρ = 0. Darhub also computes Huberty’s (1994) adjusted R2 index and Huberty’s effect size measure for multiple regression studies. Both of these indices take into account the expected value of R2.
