Computing Bivariate Correlations with PROC CORR
In most studies in which data are analyzed using multiple regression, it is appropriate to begin by computing all possible correlations among the study’s variables. Reviewing these correlations will help you understand the big picture concerning the simple relationships between the criterion variable and the four predictor variables as well as among the four predictor variables themselves.
