Help with "variables out of order" error

[Sylvie Sanou]

Hello everyone,

I am trying to estimate a treatment effect model using the Heckman's sample selection model.
Here is my code:
treatreg depressed debt_other healthgl_dum limit_work_10 Inc_10_cpi debt_Inc_V debt_educ_limit grad_cont married work_2010 insured_dum female age black BA_dum rural child_under_2010,treat (debt_educ_dum= Neg_paren_W healthgl_dum97 disable_97 paren_health_dum paren_Inc_dum tuition_ch private for-private)

When I run the regression it gives the following errors: "variables out of order r(111)"

I have double checked the order of Heckman selection model and the way I ordered my variables seems to be right.

Please, can anyone help me understand what is wrong with my code?

Thank you so much.

The error arises when you specify a variable list and the order does not correspond to the order of variables in your dataset. In your command, the culprit appears to be

paren_health_dum paren_Inc_dum tuition_ch private for-private)

where the implication is that the variable "for" does not precede "private". The help for treatreg indicates that it has been superseded by etregress.

Out-of-date command

treatreg has been renamed to etregress.

Thank you so much for your suggestion. I have renamed the variable and it works. Thank you so much.
