Help with flexmix
Hello,
I am using the package "flexmix", specifically the function "stepFlexmix"
and was hoping for some assistance:
Here is my input:
fit <-
stepFlexmix(trips~.,data=data.frame(traveldata),k=1:5,nrep=5,model=FLXMRglm(
family="gaussian"))
And I recieve the following error message:
*Error in FLXfit(model = model, concomitant = concomitant, control =...

R Package: mmlcr and/or flexmix
Greetings
I'm a relatively new R user and I'm trying to build a latent class model.
I've used the 'R Site Search' and it appears there's not much dialogue on
these packages
On mmlcr, I've gotten it working, but not sure if I'm using it correctly.
On flexmix, I can only seem to get results for one class.
I'm attaching my code below - if anyone

Latent class analysis, selection of the number of classes
Hi,
I perform latent class analysis on a matrix of dichotomous variables to
create an indicator of class/category membership for each observation. I
would like to know whether there is a function that selects the best fit in
terms of number of classes/categories.
Currently, I am doing this with the lca() function of the e1071 package.
This function requires me to specify the number of classes
