st: mi impute chained truncreg

[Leah Schinasi <SchinasiL@fellows.iarc.fr>]

Dear Statalist, 

When I run mi impute chained with truncreg and specify lower and upper limits for the imputed variable, is it possible to specify as a lower or upper limit another variable that we are trying to impute? When I try this, I receive error messages saying that the initial values are not feasible. 

Here is a simple line of code as an example:
mi impute chained (truncreg, ll(birthyear) ul(endyear)) startyear (truncreg; ll(birthyear) ul(enrollmentyear)) endyear 

Note: both endyear and startyear have missing values.

I will appreciate any insight that list members might have.

Thanks in advance!
