Abstract

predxcat calculates and optionally graphs adjusted means from linear regression models, adjusted medians from quantile regression models, or adjusted proportions from logistic regression models for one or two nominal X variables, adjusted for covariates. If a second X is specified, means, medians or proportions are calculated for all possible combinations of X categories, and an interaction effect is tested. Optionally, model estimates and/or a graph may be displayed. Dummy variables are created for xvar1. The lowest dummy variable defaults to the reference group. If xvar2 is specified, dummy variables are created for it, as well as interaction terms. This is version 3.1.0 of the software, requiring Stata version 8.
