Hello 

I am trying to adjust a logit model that was built on a 50:50 case control
sample so that it reflects the true proportion of cases this number is <
.001 of the population. I know why and how I can adjust for the intercept,
but I would like some help in locating information about adjusting the
coefficients for the covariates, or if infact if this is a good idea.


Regards


Andrew Corroll
