CORR Procedure


The CORR procedure computes Pearson correlation coefficients, three nonparametric measures of association, and the probabilities associated with these statistics. The following are highlights of the CORR procedure's features:

  • produces the following correlation statistics:
    • Pearson product-moment correlation
    • Spearman rank-order correlation
    • Kendall's tau-b coefficient
    • Hoeffding's measure of dependence, D
    • Pearson, Spearman, and Kendall partial correlation
    • polychoric correlation
    • polyserial correlation
  • computes Cronbach's coefficient alpha for estimating reliability
  • saves the correlation statistics in a SAS data set for use with other statistical and reporting procedures
  • enables you to use Fisher's z transformation to derive confidence limits and p-values under a specified null hypothesis for a Pearson or Spearman correlation
  • performs BY group processing, which enables you to obtain separate analyses on grouped observations
  • creates a SAS data set that corresponds to any output table
  • automatically creates graphs by using ODS Graphics
