Hi, When I executed my model, I got the following error message; Initial parameter values result in -LL = NaN Could any one let me know how to deal with it? Thanks!
Hi Kyang, NaN means “Not a Number” i.e. I guess LL was not calculable but why I can’t answer. Are you sure you submitted the Initial Estimates you had selected with the initial estimate tool? Otherwise they would have defaulted all to 1. If you can’t spot the issue try posting the project here. Simon
I asked around and it sounds like it’s starting with an infinite log-likelihood and better initial estimates should fix it. Did you manage to get it running?
