Hi all,

I am trying to run a nonlinear regrssion. The followings are my codes.

nonlin beta0 beta1 beta2 beta3 beta4 beta5
frml eq1=beta0+beta1*evwrd+beta2*default+beta3*dyield+beta4*term+(beta1*beta3)*dyield{1}+(beta1*beta4)term{1}+beta5*year34{-1}+(beta1*beta5)*year34
nlls(frml=eq1,trace) evwrd{-1}

I got a error message that says "## SX22. Expected Type FRML[ANY], Got RECTANGULAR[REAL] Instead
>>>>eta1*beta3)*dyield{<<<<"

I am not sure why I am getting the error message as I used same codes yesterday and they worked. Could someone please let me know what went wrong here? Thanks

Assuming that you copied that straight out of your program, you're missing the space between eq1 and the =

Thank you for pointing out the problem.
