Hi,
I am estimating Difference-in-difference model:
Y= b1Treat+ b2 after + b3 (after*post)
The effect of treatment (b3) differs by intensity of another variable x3. I want to estimate Diff-in-diff model for different levels of x3 (say at 10%, 20%, 30%......90%) and then graph the DID coefficients against the value of x3. Something like this. Is it possible to create a graph like this in Stata?Array Kindly advise.


Thanks,
Santra
