Hi,
I was looking for an explanation of why the options robust and cluster are
not available for the Tobit model but they are available for intreg. I
found in the FAQ the following post by J Hardin
http://www.stata.com/support/faqs/stat/tobit.html
He basically says that you can do some manipulations with the data to use
intreg and then obtain robust s.e. I was sondering if this is s.e are
theoretically valid? If so, why would the people at stata block the option
robust form tobit?
Any comments?
Thanks,
Alejandro
