latent class modle for rater agreement

Lisa Wang
Hello there,

I would like to test the agreement amongst 6 raters for nominal data on
a scale from 1-4, and conduct a latent class analysis in R. How should
the data be formatted and what code should I use?

Thank you very much

Typing latent class on the R project search page gives you at least four
packeges that do latent class models mmlcr, flexmix, gllm, depmix etc

This kind of agreement test seems to call for Krippendorf's alpha. See
