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.
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.
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?
