Hi, Sorry if this is a repost, I don't think it went through the first time. In tech10, how are the standardized residuals for bivariate cell counts calculated? It doesn't seem to be (OE)/sqrt(E)? thanks, Jeannie 


The standardized residuals given in tech10 are not the Pearson residuals but are the standardized Pearson residuals. See Agresti's Categorical Data Analysis book, Sections 3.3.1 and 4.5.5. The original article on this topic is The Analysis of Residuals in CrossClassified Tables, Shelby J. Haberman, Biometrics, Vol. 29, No. 1 (Mar., 1973), pp. 205220. The advantage of the standardized Pearson residuals is that they are just like standard normal residuals, while the unstandardized Pearson residuals are less variable. For the bivariate tables these are computed by (OE)/[sqrt(E)*sqrt(1E/n)].

Is it true that when sampling weights are used in LCA fitting, the Pearson Chisquare statistics for model fit in the general output and for response pattern frequencies in TECH10 are no longer valid? Is that why some of the Chisquare values in TECH10 become negative? 


The response pattern frequencies in TECH10 do not take weights into account. This could be why some of the chisquare values become negative. In the future, TECH10 will take weights into account. 


Hi, I am running a latent class analysis with 10 binary indicators and sample weights. If the tech10 output (the bivariate residuals) does not take account of the sample weights (as mentioned in the post above) how can I assess model fit? thanks 


The current version of Mplus takes the weights into account for TECH10. 


Thanks Linda. Just to check  by current version do you mean 6.11? I'm currently using version 5.21. 


Yes, I mean 6.11. I don't know what it was in 5.21. You can run it both with and without weights to see if TECH10 differs.

Hello. I am running a GMM negative binomial model and I would like to examine the standardized residuals; however, the section of the output where the tech 10 results should appear is blank (except for the heading "technical 10"). Is it possible to obtain standardized residuals with the negative binomial? Thank you. 


Are you using version 6.11?

I was not, but I have since updated my version to 6.11 and it has not resolved the issue. Thank you again.

Dear Dr. Muthen, I am running a CFA model using MLR for parameter estimation. The data structure includes a booklet design (i.e., data missing at random), and both 72 categorical indicators (binary responses indicating an ability factor) and 72 continuous indicators (logtransformed response times indicating a slowness factor). To obtain model fit information for the categorical dependent variables in the model, I wanted to look at TECH10 for the standardized residuals. However, with a higher number of indicators the TECH10 Output disappeared. When I used 6, 9, or 15 indicators per factor TECH10 was regularly provided. With about 30 Items per factor it wasn’t. How do I get TECH10 in this case? Thank you in advance! With kind regards, Annette 


We don't provide TECH10 for large frequency tables. You would get the following message if this is the case: TECH10 OUTPUT FOR CATEGORICAL VARIABLES IS NOT AVAILABLE BECAUSE THE FREQUENCY TABLE FOR THE LATENT CLASS INDICATOR MODEL PART IS TOO LARGE. 


Thank you for your quick answer! This message didn´t show up in my outputfile, however just „TECHNICAL 10 OUTPUT“ was written in the last output row: "TECHNICAL 10 OUTPUT Beginning Time: 10:25:13 Ending Time: 10:25:30 Elapsed Time: 00:00:17..." How do I compute the model fit information in my case?

what does output of TECH10 of latent class model refer to? how to interprets? 


Study the short course Topic 5 handout and video on our website. 


Thanks a lot... I will do 


ok.

Hi I'm trying to estimate standardized residuals for a path model. The independent variable is a manifest variable, mediators are latent variables, and the dependent variable is a manifest dichotomous variable. I was wondering if fit indicators were available when using ML as estimator (logit link) and realized that it was not. I was told that you can compared observed vs. model estimated frequencies and standardized residuals. When I included tech10 in the output line of the .inp file, I received an error message: TECH10 OUTPUT FOR CATEGORICAL VARIABLES IS NOT AVAILABLE FOR MODELS WITH COVARIATES. The error would not go away when I removed the covariates from the model (so all that was left was the one IV, 2 latent variable mediators, and the binary dependent variable). I would appreciate assistance and getting tech10 to work. Thank you! 


TECH10 would be relevant if you have more than one categorical DV. ML with categorical outcomes does not have fit indices. You can try Bayes which uses probit but the power of it test of model fit has low power. One approach in the ML context is to create neighboring models that are less restrictive than the model you consider and then check if the extra parameters are significant. 


I am trying to compare a series of CFA models with 60 categorical indicators, and therefore using MLR estimation and montecarlo integration. The chisquare test cannot be computed because the frequency table for the categorical variables is too large. So, I included TECH10 in the output, but the TECH10 output for the categorical variables is not available because the frequency table is too large (but there is model fit information). Do you have any suggestions/recommendations for how to compare models in this case? Also, could you point me to resources to interpret the TECH10 output that is available? Thank you! 


If the models are nested (which can be checked using our new NESTED option in version 8.1), you can use chisquare difference testing based on the logL values. Also try the Residual option in the Output command. What is unclear about your Tech10 output? 


Thank you! I found the difference testing instructions on the mplus website. I will also try the residual option. For the Tech10 output, I was unsure about what values I should examine to evaluate fit. My guess would be the univariate loglikelihood? Thank you again for your time! 


You want to look at the standardized residual column which gives ztests, so you look for values greater than 1.96 in absolute value. This is for each response pattern, for the univariates, and for the bivariates.
