Hi,
I know that ivtobit works well with a dummy endogenous
variable but I am not sure if
Is it ok to use ivtobit when the endogenous variable is a
limited dependent variable? More precisely suppose that for
30% of the sample the endogenous variable takes the value 0
and for the rest it has a positive value (the distribution
of zeros in the endogenous variable is different to the
distribution of zeros in the dependent variable).
Thanks for your help.
