comment How can I determine statistical significance in an A/B test in which the KPI is dependent upon two variables - one bernouli and one continuous?
@Brian I fixed the bootstrap after sleeping on it. Feel free to ask questions if the Stata code does not make sense.

@Brian I am not aware of any non-Stata implementations. Hacking together the marginal effect is pretty easy, but getting the standard error is non-trivial. At first, I thought that it would be easy enough to boostrap, but that is not working for some reason. I have added code.

A two part model is what you're looking for.

comment How to merge datasets in STATA conditionally?
Translate the Stata date to tm format and merge on that. Alternatively, consider using the Aruoba-Diebold-Scotti Business Conditions Index, which is at a higher frequency.

This sounds like a simple merge m:1 date using CFNAI.dta.
