Thanks for the appreciation. I have now uploaded a more permanent Stata 12 version of -punaf-, which you can download from my website by typing, in Stata,

net from "";

and selecting and installing -punaf-. The new version adds a new option -atzero()-, which specifies Scenario 0 just as -atspec()- specifies Scenario 1. Therefore, the -punaf- package can be used to estimate rate ratios between 2 fantasy scenarios using a logit, probit or loglinear model, such as a fantasy world in which everybody smokes and a fantasy world in which nobody smokes. Previously, we could only compare fantasies with reality.

I will send this new version to SSC when Kit Baum returns. Let me know if there are any problems.

Best wishes
