How may I calculate the pseudo R-square in surveylogistic? I have seen lackfit in proc logistic, however, I need to use class and cluster by surveylogistic as well.

See the RsquareV macro, but note that it is not clear if there are any issues with using this statistic with survey data. See the Zhang reference for details on the method used and to make your own determination on its appropriateness.
