Dear statalist,

I am triying to imput rental prices for houses to a sample using some
characteristics of the construction which are shared between my data
and the data in another database in which rental prices are declared.

When i use OLS i get negative fitted values both in the original
database as in my database.

How can ensure that the predicted values will be non negative?

Thank you very much in advance.

Laurie
