I have come across a wrong error message.
The variable -novar- does not exist.
. duplicates drop patkey date if novar !=.,force
varlist not allowed
r(101);
. duplicates drop patkey date if date != .,force
Duplicates in terms of patkey date
(38 observations deleted)
I suspect that -novar- is passed as a macro and generates this message
because it is missing.
It took a while to figure all of this out. So fixing the message might
be of help to others.
