Hi ya, thanks a lot everyone!! I changed rr:ii-1 to rr:(ii-1) and the code works!!! I finally get some estimates from the optimization function (i am doing a logit model with 2 segments). Thanks thanks!!! I didn't realize rr:(ii-1) and rr:ii-1 would make such a big difference, especially because the professor used rr:ii-1 in his Gauss code. I didn't realize it means so much different in R!
