SAS BISERIAL macro: Compute biserial, point biserial, and rank biserial correlations. Computes biserial, point biserial, and rank biserial correlations between a binary and a continuous (or ranked) variable. The biserial correlation measures the strength of the relationship between a binary and a continuous variable, where the binary variable has an underlying continuous distribution but is measured as binary. If the binary variable is truly dichotomous, then the point biserial correlation is used. The rank biserial correlation measures the strength of the relationship between a binary and a rankings (ordinal) variable. The BISERIAL macro produces only an output data set.
