Is there a way to save residuals as data for analysis in another program? (e.g., SPSS)
Is there a way to reanalyze residual data in Mplus? I'd like to run a CFA and then an EFA on the residuals to analyze the parts of the model that don't fit well.
Thanks for your help, and have a great day.

| If you mean residuals for each individual - no. You can request RESIDUAL in the OUTPUT command. |

Thank you for your prompt reply.
Is there a way of saving the residual matrix as a datafile?
Is there a way to reanalyze the residual matrix within Mplus? For example, after running a CFA I'd like to analyze the residual output in an EFA.
Thanks again.

| You cannot save the residual matrix in Mplus. You could edit the output to create a file and analyze it using the TYPE option of the DATA command. |

Hi,,
Does Mplus 6.1 provide a data file for Level 1 and Level 2 residuals?
If not how can we utilize Mplus in order to test the multilevel model assumptions for categorical outcome variables?
Thanks... |

|
|
| Which assumptions do you want to test? |

| Linda,, I want to test the independence of residuals for different levels and also the independence of residuals for different units in the same level. |
|
|
|
|
| What is your model? |

I have a two-level structural model in which I test the relationships among 5 latent variables at the student level and 3 latent variables at the classroom level. The factor indicators which define the latent variables are categorical.
I also think to check multivariate normality, however, I would not be able to use MAHALANOBIS option of Mplus, since I have categorical outcomes.
For power analysis with categorical outcomes is Monte Carlo study appropriate or such simulation studies specific to continuous variables in Mplus?
Thanks... |

There is no assumption of normality of categorical items. Categorical data methodology takes into account floor and ceiling effects.
Monte Carlo studies are appropriate for any scale type. |

Thanks Linda,, I have a follow up question.
Mplus does not save a file for residuals.In order to test the independence of residuals for different levels and the independence of residuals for different units in the same level with respect to the two-level model above can I save residual files in SPSS and use it as a .dat file in Mplus?
Or there is no need to test these assumptions with categorical factor indicators using Mplus?
Thanks... |

| Mplus does not give residual on the unit level. |
