Hello!

I am working on a panel dataset.

I want to create a dummy variable that indicates weither my hp trend variable is increasing or declining for each country (Dummy =1 if trend is increasing for country i and 0 if declining).

How I can do this in stata? I believe I have to start with the gen Dummy=1 if ...

I don't know what to use after " if " for that condition.

Thank you in advance.
