Dear stata users:
        I am a new user of stata.I can do simple linear regression.To
nonlinear regression, I do not know how to do.For example, two
equations follows as:
    lnII=a+(blnAFR+clnPPE)*exp(d*TIME)+error
   lnII=a+(blnAFR+clnPPE)*exp(d1*TIME+d2*TIME*TIME)
   How to write stata command to run these regression separately.
  Forward to your reply! Thanks!
 Kind regards!
