The point I made was that you almost never have to reinvent
that operation yourself, there are many tools inside Stata
that do it for you. Which tool is right for you depends on
your situation. I used -predictnl- as an example because it 
is a common situation where one might be tempted to perform 
that operation. If you tell us why you want to perform that 
computation, we can tell you if there is such a tool 
available that is appropriate for your situation.
