Dear Martin,

Please see attached article where I found that correction of bias needs
to be done after antilog transformation.

Kind regards,
Dejan

This post is way too terse. Most people throw variables in logs to bring
the
dependent closer to normality. What kind of a "bias in regression
estimates"
are you talking about?

Dear Statalist member,

I have transformed the variables using log function before regression.

Do you know by any chance which function in Stata or some ado file can
perform antilog transformation after regression with correction for bias
in regression estimates? 


Thank you in advance

Dejan
