I am running a two-level model with one latent variable both with effects within and between (outcome variable is continuous). This variable is a dummy variable (4 categories, so I have 3 dummies). As my latent variable is 0/1, a pearson correlation with the dependent variable would not be possible. So, where does the output of the correlations come from? I cannot reproduce these correlations in SAS or R (neither from the original variables nor from my proc mixed/lmer/stan_glmer multilevel regression outputs) but need to understand where they come from and why they are so different from the other regression outputs. Thanks a lot for your help! |

Sampstat gives correlations among observed variables (no latents included). It's unclear what your model is. You say "this variable is a dummy variable" - it sounds like "this" refers to your latent variable, that is, you have a mixture model. |

Hi, That's right, my dummy variable is my latent variable. This variable actually causes some convergence problems (I'll have to take a look at that too). My question is, why if it's the same dataset, do I see such different correlations between the observed variables than in SAS and R? I'm having a hard time understanding the calculations behind this output. Thanks! |

Please send your Mplus output and that of SAS/R (using a pdf) to Support along with your license number. |

Hi Linda and Bengt, I have another question regarding the type of correlations in my output. I am using model estimator MLR in a model with covariates. Does this mean the correlations from the SAMPSTAT are probit residual correlations? (as suggested in the user's manual Ch.18?) Thank you, Carolina |

That depends on whether you specify some variables as Categorical. If you do, and you use WLSMV, then yes they are probit residual correlations. |
