Jose Maria asked: "would it be possible to use *predict pr, pr* instead of *margins*? If there are only a few discrete covariates, then you can graph or table all the predicted probabilities. Otherwise -margins- is preferable, I think, especially when followed -marginsplot-. My own strategy, when the choice is mine, is to fit -svy: logistic-,This will (almost) always converge with no difficulties. Then I look at -marginsplot- of predicted probabilities; I add two-factor interactions and see what happens to the plot For most studies, I prefer to describe effects in terms of linear differences in predicted probabilities, even if the underlying model is -logistic- with no or few interactions.
