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

Hi Folks
Does anyone know a stata command that can be used to get a linear
combination of predicted values and its SE or SD or CI?.
