Hello,
I'm trying to use the psmatch2 command to evaluate paired differences in differences for 2 periods of time with different individuals in each year. We are trying to generate a delta value that captures the evolution in the outcome variable before and after the intervention between the treatment group and the control group in the zone of common support (𝑌𝑖2 − 𝑌𝑖1). Our outcome variable is a dummy. However, when I generate the delta value I get an empty variable(all values missing). Anyone knows if it is possible to do a paired t test when the outcome variable is a dummy?
