Creating a variable to mark an intervention

[Natalie Chwalisz]

Hi

I have a time series data set with three variables: CodedOffense, dm, and count (coded offense summarized by month). dm is my time variable, and it ranges from 2012m1 to 2020m7.

I would like to create dummy variable for when the intervention started (August of 2018) , and then expanded (October 2019). I tried different codes, but I seem to get the syntax wrong each time.

Thank you for any advice you may have!

Assuming that you properly declared your time variable as year-month

gen wanted= inrange(dm, tm(2018m8), tm(2019m10))
