...uot; contains all predictors for all planning units.
I used the following commands: "stepmodfi" is the output of the stepwise approach
predictionlogit <- predict(stepmodfi, predallx, type="link", se.fit=TRUE)
upperlogit <- predictionlogit$fit + 2*predictionlogit$se.fit
lowerlogit <- predictionlogit$fit - 2*predictionlogit$se.fit
upperresponse[,i] <- exp(upperlogit)/(1+exp(upperlogit))
lowerresponse[,i] <- exp(lowerlogit)/(1+exp(lowerlogit))
