Hello!
I'm conducting a project utilizing a Difference-in-Differences (DiD) framework to investigate the effects of a policy implemented in a staggered manner across various states and years.
Below is my regression model and the associated code. Now I want to perform a placebo test grounded on this baseline regression, but I don't know how to do that in Stata. Thanks!
y=a1*treat*post+controls+FE
code: reghdfey treat*post $controls, absorb($fixed_effects) vce(cluster fips)
