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 (o...

Please can someone explain to me how to use randomLCA in R for an analysis. I tried using it and had this error (copied below) which indicated my patterns must consist of 0 or 1. I assume I am doing something wrong. Please help. > library(lattice) > library(boot) Attaching package: ‘boot’ The following object(s) are masked from ‘package:lat...

A new package 'randomLCA' is available on CRAN. Its main purpose is to fit latent class models with random effects, such as those used in diagnostic testing. This methodology can also be applied in other areas. It also fits standard latent class and will plot. Ken _____________________________________________...

What's the best approach to running latent class analysis with R? I've downloaded both randomLCA and poLCA packages, but I am interesting in running a standard LCA with individual records (not frequency table) as input data.

Dear R users, I would like to perform Latent Class Logit Models for the analysis of choice experiments in environmental valuation. This kind of analysis is usually performed with NLogit Software (http://www.limdep.com). I attach the results I usually obtain using NLogit and NLogit model specifications. For Random parameter models and Logit Models I usually perform my analysis with the package
