Hi.

I wonder if someone can help me as I'm loosing my mind here!
I want to use ITS (itsa command) to estimate an intervention effect, taking into account the age and sex profile of participants. I cant seem to set up the dataset correctly as I cant tsset it no matter what I do. I was entering in the same month year in several rows to account for age group and sex, but should it literally just be one row per month as it keeps telling me I have repeated values within panel. How then do i adjust for covariates?

Thanks for any help you can give me!
Eimir
