Hi! I want to use the factor mixture modeling. but the item of one factor are CATEGORICAL,another are continuous.Can I use the factor mixture modeling analyse my data? thank you! ######## the code : VARIABLE: NAMES ARE u1-u30 t1-t30; CLASS=C(2); ANALYSIS: TYPE=MIXTURE; ESTIMATOR=MLR; STARTS = 100 20; PROCESSOR=2; MODEL: %OVERALL% ab BY u1-u30*; sp BY t1-t30@-1; ab@1; sp@1; ab with sp; u1-u30 PWITH t1-t30; %C#1% ! [ab*]; [sp*]; |

Add a question on the content above: how can I set the Correlated residuals Between continuous and CATEGORICAL variables? eg:u1-u30 PWITH t1-t30; thank you for your help! |

With ML, it is very hard to do these correlations - you have to create a factor for each of them and you have to use numerical integration which can't be done with so many factors. Bayes is a possibility and there you simply use PWITH. |

Yes, having different measurement scale types presents no extra consideration. |

thank you for your help! when I use bayes to estimate the model, I do not know how to save the latent variable and the class latent variable from your mplus guide? thank you! |

With Bayes you get a distribution for each subject (so like imputation), that is, the nominal variable gets proportions for each category - plus you get the most likely class. See the FAQ on our website: Cprobabilities with Bayes |

thank you! when I set the Correlated residuals Between continuous and CATEGORICAL variables,I found that" THE MODEL CONTAINS A NON-ZERO CORRELATION BETWEEN DEPENDENT VARIABLES. SUCH CORRELATIONS ARE IGNORED IN THE COMPUTATION OF THE FACTOR SCORES.". If I want such correlations affect the factor scores ,how can I do it? Thank you for your kindness! |

This should not be a problem using Bayes (unless your Categorical variable is declared as Nominal which Bayes doesn't cover). |
