I'm finally figuring out what I'm doing with the ZIP models and the last thing I need to do is get a table with predicted values for the dependent variable. NLMIXED doesn't appear to like an OUTPUT statement. Could someone tell me how to get a table with both the original values and predicted values?

Thanks,

Jeff

Below is the SAS code for the NLMIXED procedure

proc nlmixed data=inbu; parameters a0=0 to 1 by .2 a1=0 to 1 by .2 b0=0 to 1 by .2 b1=0 to 1 by .2; linpinfl = a0 + a1*TK; infprob = 1/(1+exp(-linpinfl)); lambda = exp(b0 + b1*TK); if round=0 then ll = log(infprob + (1-infprob)*exp(-lambda)); else ll = log((1-infprob)) + density*log(lambda) - lgamma(density+1) - lambda; model density ~ general(ll); output out=temp; run;
