Yes I'm aware that there are different kinds of standardized residuals available with logit models. I'm interested in deviance or pearson residuals.

What is a residual is and how to standardize it is no longer a
straightforward question in models like -logit-. As a
consequence many different "standardized" residuals exist. So
what flavor of standardized residuals do you want? Don't
answer "the right one", as that flavor does not exist or is
discipline specific
