Helen, You may consider using LCA 1.1, written by Niels Waller at Vanderbilt University. You may need to get it from his website at Vanderbilt instead of CRAN, at least it was the case in the past. Tim Liao ---- Original message ----

available that
will estimate a 2-class Latent Class Analysis, with trichotomous observed variables, some of which are free to covary. I have read the PDF files regarding the e1071 and gllm
packages, but it
appears that these only allow dichotomous measured variables,
and it is
not clear to me whether they allow the measured variables to
covary.
Thanks! Helen Dennis Education Associate Assessment and Analysis Group Delaware Dept. of Education 401 Federal Street Suite 2 Dover, DE 19707 hdennis at doe.k12.de.us tel: 302-739-6700 fax: 302-739-3092
