Hi, I did an LCA using 38 categorical indicators and 337 observations to fit a 3 class model. I wanted to use the likelihood ratio chi2 to explore adequacy of model fit but I keep getting the following message: THE CHI-SQUARE TEST IS NOT COMPUTED BECAUSE THE FREQUENCY TABLE FOR THE LATENT CLASS INDICATOR MODEL PART IS TOO LARGE. Are there any other options? tks, |
|

The chi-square test referred to is for the multiway frequency table for the categorical variables. This test works well for 8 or fewer variables. With 38, the table is too large. You can look at TECH10 to assess model misfit. |

Thanks for the recommendation. However,when I added "tech10" I found the tech10 output was empty (using MPLUS 5.2) |
|

TECH10 was added in Version 5.2. It sounds like there may be a problem for your situation. |

Hi, I solved the problem and got the tech10 output. I'm not sure which column I should be looking at in the bivariate model fit results (residuals between pairs of indicators). Is it the last one with the standardized residuals (z-score)? If so, is the -/+ 1.96 an appropriate cut-off point for an alpha =0.05? tks |
|
|
Yes, you should look at the standardized value which is a z-score and use appropriate z-score cutoffs. |

Great thanks! In relation to tech11 and tech14 outputs; can the likelihood values for the Vuong-Lo-Mendell-Rubin and bootstrapped ratio tests be exactly the same? |
|
|
They typically are not. |
