Package for Clustering - Query
Dear R users,
Is there any package for Latent Class Analysis (to be used in a clustering
application) which supports mixed indicator variables (categorical and
continuous)?
Alternatively, is there any other clustering algorithm available that
supports this type of data?
Thanks in advance for your help.
Regards,
Lars.

Ordinal response model in depmixS4
I am running a latent class regression with 3 nominal and 2 ordinal variables using depmixS4 but the available response models do not include one for ordinal response. How do I go about this?

stripping #s in a text file prior to reading into table or dataframe
I'm importing a lot of text tables of data (from Latent Gold) that includes
hashes in some of the column names ("Cluster#1", "Cluster#2", etc.). Is
there an easy way to strip the offending hashes out before pushing the text
into a table or data frame? I thought I'd use gsub, e.g., but can't figure
out how to read in a text file without reading it into a table or

latent class modle for rater agreement
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

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

mixture models/latent class regression comparison
Dear list,
I have been comparing the outputs of two packages for latent class
regression, namely 'flexmix', and 'mmlcr'. What I have noticed is that
the flexmix package appears to come up with a much better fit than the
mmlcr package (based on logLik, AIC, BIC, and visual inspection). Has
anyone else observed such behaviour? Has anyone else been successful
in using the mmlcr

Latent Class Logit Models in discrete choice experiments
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

Latent class multinomial (or conditional) logit using R?
Hi everyone?
Does anybody know how can I estimate a
Latent class multinomial (or conditional) logit using R?
I have tried flexmix, poLCA, and
they do not seem to support this model.
thanks in advance

Latent Profile Analysis Package?
I´ve several packages for latent class analysis, but I was wondering if there is a package for continuos variables, which allows latent prfile analysis.
Thanks for your help in advance,

finite mixture modeling
Hi all,
I have a question, is there any R package dealing with latent transition analysis with both categorical and continuous indicators? So far what I found from GOOGLE are only packages dealing with latent class analysis. So what about the longitudinal situation? Any way we could look at the transition from one class to another across time points?
Thank you very much.

run latent class analysis with R
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.

finite mixture model (or latent class)
Dear Listers,
My post might be somewhat OT.
Currently, I am trying to use flexmix to build a finite mixture model.
For instance, I am getting the prior probability and coefficients for
each latent class from training data. Is there a way to get the
posterior probablity and prediction of a new dataset?
What I am thinking is to apply the prior prob and coefficient from
training set to testing data

Vermunt's LEM in R
I don't know of any R package that can match all the functionality of LEM
eg fitting equality constraints to model parameters a la LISREL.
WRT dumping tables, I would have thought that as.data.frame.table does
pretty much what you want, [not tested]
newtab <- as.data.frame(table(a,b,c))
cat("dim\n")
for(i in seq(1, ncol(newtab)-1) {
cat(nlevels(newtab[,1]," ")
}

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

Mover Stayer Models
Does anyone know how to program mover stayer models in R? They are a type of Markov chain model where there is a group of people who stays in the same place, a group who always moves, and a group who does both.
Thanks.

Estimating a latent class multinomial logit regression with flexmix
I am trying to estimate a latent class multinomial logit regression with
flexmix.
I am not sure if I should do it as follows:
m4<-flexmix(cbind(y,1-y)~x1+x2|id,model=FLXMRglm(family="binomial"),data=NPreg,k=2)
,
where id links each row with the corresponding respondent.
Each respondent has 4 alternatives to chose from.
y takes the value 1 only for the alternative chosen;

mapping states with colors

I'm just learning how to use maps. As an initial foray, I'm mapping the
states that have "duty to retreat" (blue) and "stand your ground" (red)
self-defense standards. Here is my extremely naive script:

Non-linear regression with latent variable
Hi
Can anyone please suggest me a package where I can estimate a non-linear
regression model? One of the independent variables is latent or unobserved.
I have an indicator variable for this unobserved variable; however the
relationship is known to be non-linear also. In terms of equations my
problem is
y=f(latent, fixed)
q=g(latent) where q is the indicator variable
For me both f and g are

simple graph question: manipulating variable names
This is a simple problem that has stumped me: I'm trying to loop through a
few dozen variable names in graphs. I've tried various approaches like
this:

dvs <- c("onedv", "anotherdv", "yetanotherdv")
for (iv in ivs) {
for (dv in dvs) {
