I'm pretty new in R... try to learn ASAP for a project, I wonder if anyone can provide some advice on which package to use when fit Mixture regression model with both categorical(more than two levels) and continuous variables. I tried to use Flexmix... and transposed the multi-level variables as several 0-1 dummy variable and tried to put in the package and find the fit. But it always tells me can't find the mixture model convergence.. I guess I must do something wrong, does the # of variables matter? Say if I have 13000 observations and 50 variables, will it work?
