I used the stata version 16 to implement double hurdle model.
I found 2 commands for implementing the double hurdle model.
1) craggit depvar1 [indepvars1] [if] [in] [weight], second(depvar2
[indepvars2]) [options]
2) dblhurdle depvar [indepvars] [if] [in] [weight], {ll(#)|ul(#)}
[options]

I would like to know how is the difference between these commands?

I would really appreciate the help with this, I am new to STATA!
