I am quite new to STATA. I need to do a post-hoc test to determine which pairs of adjusted means differ significantly in an ANCOVA with one categorical variable and 2 continuous covariates. I know how to do a post-hoc in STATA for a one way ANOVA, but I can't figure how to do it for ANCOVA. Incidentally, I have calculated the adjusted means in the "Postestimation".
So, does anybody know how to do post-hoc pairwise comparison like Scheffe or Bonferroni for ANCOVA in STATA?
