SVYPXCAT: Stata module to calculate predicted means or proportions for nominal X's for survey data
Joanne M. Garrett
svypxcat calculates and optionally graphs means from linear regression models or proportions from logistic regression models corrected for the survey sampling scheme (weights) for one or two nominal X variables, adjusted for covariates. If a second X is specified, means 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.
