Hello all,
Good day,
I am to stata and trying to  learn using  stata 11. When I try to
apply the ptrendi stata command getting the following error:

 ptrendi 12 34 1\ 34 56 2\ 43 54 3
unrecognized command:  ptrendi
r(199);

 ptrend 12 34 1\ 34 56 2\ 43 54 3
unrecognized command:  ptrend
r(199);

What could be the problem?

Huu
