Thanks a lot Brian! It worked when I removed the space in the scalar statement. Yonas ____________________________ ----- Original Message ---- From: Brian P.

When I try to run the nlsur regression, Stata generates an error message (nlsuryonquaid returned 109-verify that nlsuryonquaid is a function evaluator program). Below is the function evaluator program I wrote and I would appreciate it very much if somone can help me figure out what the problem is. Thanks, Yonas program nlsuryonquaid version 11 syntax varlist(min=12 max=12) if, at(name) tokenize `varlist' args w1 w2 w3 w4 w5 lnp1 lnp2 lnp3 lnp4 lnp5 lnp6 lnexp tempname a1 a2 a3 a4 a5 a6 scalar `a1' = `at' [1,1] scalar `a2' = `at' [1,2] scalar `a3' = `at' [1,3] scalar `a4' = `at' [1,4] scalar `a5' = `at' [1,5] ... -------------------------- The space between the matrix name and the left bracket in your scalar definitions could be the source of the r(109) errors. When subscripting a matrix, you can't have a space between the name and the subscript: . mat b = (1,2,3) . sca a = b [1,3] type mismatch r(109); I'd try removing the spaces between `at' and the left bracket in all your -scalar- statements. IE, write scalar `a1' = `at'[1,1] and so on instead of scalar `a1' = `at' [1,1] // sic, not valid -- Brian Poi -- brian@poiholdings.com * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
