Contrasts, pairwise comparisons, and margins
Contrasts, pairwise comparisons, marginal means and marginal effects let you
analyze the relationships between your outcome variable and your covariates,
even when that outcome is binary, count, ordinal, categorical, or survival.
Compute adjusted predictions with covariates set to interesting or
representative values. Or compute marginal means for each level of a
categorical covariate. Make comparisons of the adjusted predictions or
marginal means using contrasts. After fitting almost any model in
Stata, analyze the effect of covariate interactions, and easily create plots
to visualize those interactions.
