This time I will try to make my request a bit clear.
I have watched many tutorial videos about PSM model in stata but all of them explain examples with ready treatment variable. but my difficulty is how to create a treatment variable.
in the meantime i m confused about the command it self because some analysts use pscore command and some use psmatch2.
Accordingly, i need to learn how to generate the treatment variable. in addition, the right command.
I am so sorry for being not smart enough
