Wilson confidence intervals for proportions

[lcmichael_unc]

I need to report confidence intervals for proportions and proportion differences using the Wilson-score (also called Newcombe) method but I cannot use PROC FREQ because the proportions are output as predicted values from a logistic model. The algebraic algorithm could be incorporated into a data step but it's pretty messy - has anyone already created code to do this. Many thanks.
