Churdle exponential margins

[Filippo Oncini]

Hi everyone,

I am running a double hurdle model with Stata14 using churdle exponential command.
I would like to have separate margins for the probit and for the exponential part of the model, but I am having difficulties with the latter.
How can I separately obtain the model for the exponential part?

I know that in the case of churdle linear same coefficient can be easily obtained running a probit and a truncated regression separately. But how does it work with churdle exponential?
Any help is appreciated.

Thanks,

Filippo
