Hi, I'm trying to run a multiple group MIMIC model that has censored indicators for the latent factor. I have three covariates and would like to use the TYPE = MISSING command, but the program will not run and says to use TYPE = MIXTURE with KNOWNCLASS, but this causes one of the factor loadings to be negative and the program will not run when I try to model the covariates, it says that the latent factor is not a latent factor. Any suggestions? Thanks 


You will need to send your full output, data, and license number to support@statmodel.com to get an answer to this one.

I am running a MIMIC model as an alternative to a multigroup model ESEM (using data from your example 4 in your addendum for versions 5.1). TITLE:MPEX4 MIMIC 4c F1F2 on group; DATA: FILE IS example4.dat; VARIABLE: NAMES ARE y1y10 group; !GROUPING IS group (1 = g1 2 = g2); MODEL: f1f2 BY y1y10 (*1); f1f2 on group; OUTPUT: TECH1; tech4; mod(0); sampstat; Is it possible to merely allow the grouping variable to be correlated with the EFA factors? I tried replcing the line: f1f2 on group; with each of the following: f1f2 with group; group with f1f2; but got the following warnings THE STANDARD ERRORS ... AN INDICATION OF MODEL NONIDENTIFICATION. CONDITION NUMBER IS 0.896D12. PROBLEM INVOLVING PARAMETER 43. (parameter 43 is the variance of the grouping variable) 


I think the message is because group is a binary variable and the mean and variance are not orthogonal. If you obtain standard errors, you can ignore this message.
