I am trying to run a NLS model and SAS gives me strange error messages.
lncompwin is the dependent variable but it doesn't get recognised. Why?
proc nlin data=dis;
parameters a=1 g=-1;
model lncompwin=(-a/g)*ln(1+a*t);
run;
ERROR: Cannot find a library containing subroutine LN.
ERROR: no dependent variable specified.
