I have tried several mixture models. However, it is almost impossible to have a global solution. I have tried to increase the starts sets up to 1000 100 with 20 stiterations. However, it does not solve my problem!!! the final loglikelihood was not still a global solution. I have followed the user book and checked whether the parameter estimates are similar except two parameters (the mean of SI and QI). Can I use the solution with the highest loglikelihood??
