Re: st: Stata command to get linear combination of predicted values after regression

["Roger B. Newson" <r.newson@imperial.ac.uk>]

If you have Stata Version 12, and want to estimate specifically a 
difference between mean predicted proportions under 2 scenarios, then 
you might use the -regpar- package, which you can download from SSC. The 
-regpar- package estimates the difference between 2 scenario proportions 
(known as the population attributable risk or PAR), and calculates the 
confidence limits using the Normalizing and variance-stabilizing 
hyperbolic arctangent or z-transformation.

I hope this helps.

Best wishes

Roger
