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 package? I ask because I am interest...

existing package (mmlcr) modification -- appropriate process?
All: I am new to R and would like your help in identifying the appropriate process to follow in order to modify the output from an existing package. I've had difficulty finding an answer online, perhaps because I am using incorrect terminology. A package that I am using (mmlcr) invokes another package (multinom). An output of multinom is the standard errors, but this output is not provided within mmlcr. I would like to obtain the standard errors as an output of mmlcr. For your reference, this is relevant code that I identified in mmlcr, using getAnywhere{mmlcrfi...

Extracting individual parameter estimates from mmlcr
I am new to mmlcr and am working on a latent class mixture model attempting to identify the trajectory and number of classes that best describes my data. I am able to find model parameters such as degrees of freedom, loglikelihood, and BIC. For example, here is a cubic 3-class model I am using. mmlcr1 <- mmlcr...

bug in mmlcr ? (PR#10576)
Hi the list. Is there a bug in mmlcr package ? The following code does not compile: mmlcrTest <- function(dataW){ dataL <- reshape(dataW,idvar="id",timevar="T",varying=list("T0","T1","T2"),direction="long",v.names="score") resultR <- mmlcr(outer= ~ 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 is familiar with either of these packages, I'd really appreciate some assistance or direction. I'm also at...

Dear List, Does anyone have experience using mmlcr Package? I am working on a longitudinal dataset. The model fitting is fine. However, I had a problem with the command "plot.mmlcr". It seems to me it can not plot a very nice trajectory plot for longitudinal dataset. I wonder whether somebody can share the experience, i.e. how to make a n...

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 Lisa Wang Princess Margaret Hospital Biostatistics tel:416 946 4501
