I have problems working out what the issue is here. 

-extremes- from SSC does no testing. It is just 
a display command. But you haven't got there yet. 

I doubt that your -regress- command was what you typed
here, as it is illegal as it stands. 

By -predit- you evidently mean -predict- but 
if the -regress- was illegal it is not easy 
to work out what the -predict- was working on, 
possibly the results of your last _legal_
modelling command. 

The FAQ advises 

"Say exactly what you typed and exactly what Stata 
typed (or did) in response. N.B. exactly! If you can, 
reproduce the error with one of Stata's provided datasets 
or a simple concocted dataset that you include in your posting."
