Can anybody, please, explain me how many parameter are estimated using
randomLCA?
For examples, model "dentistry.lca2random" estimate 1 scale (or
variance, b_j) parameter and 2 position parameters (a_cj)? Doesn't
it?
Do I need at least 4 diagnostic tests for such a model?
What happens if I specify options blocksize and byclass? How many
diagnostic tests (or rater) I need?

I want to include sample weights in the model, I have read that poLCA does
not take into account weights, but when I introduce them, it seems that the
model is running correctly. This is the command I am using:
lca2 <- poLCA(substances, ena, nclass=2, graphs=TRUE, maxiter=2000,
(weights=p_adicc))
my question is, if the results are really taking into account the weights ?
if not, how can I introduce weights into my analysis?
Thank you for your help.
