How to do PPML in this imputation based estimator #19

Closed BashirMohammad closed 7 months ago

Can we include model of Y(0) as a non-linear function such as poisson? I was thinking of this because I have to take logs but my outcome has many zeros as well. Is there an imputation based version of xtpoisson? Thanks

Hi, Not with did_imputation but Jeff Wooldridge has a great paper about that.
