Levy extended Dunnett's procedure for multiple comparisons to include contrasts defined on proportions, variances, and product-moment correlations. In the present article, an SAS program that uses Levy's method for conducting many-one pairwise comparisons among proportions associated with k independent samples is described. An example from Introduction to Design and Analysis by Keppel, Saufley, and Togunaga was used to illustrate the final analysis of a computer run conducted with this program.
