Hello Stata users,
I have a panel data with three waves collected during 2011, 2013, and 2015. I want to evaluate a policy reform made in 2013. My outcome variable is income in USD and the variable of interest is the interaction of gender and post reform period. Gender comprises 1=male and 0=female. The reform period=1 if year >=2013 and 0 otherwise. I want to test the parallel trend assumption using a graph. How could I implement it in Stata? Appreciating your support, here comes some information about my data.
[CODE][CODE] gen post2013=year>=2013
