Fitting a causal forest with a count response variable

[aczura2024]

I am interested in using causal forests for a response count variable (y=0,1,2,3,...). However I have not yet found a way to implement this. Any suggestions?

Thanks in advance!

How about using a Poisson regression or log-linear model, like a convention usage on quantity sales? I think the easiest way is to just doing a log-transform on the outcomes. Then you can continue on standard causal forest.
