Hi Linda, We have just noticed something that puzzles us a bit about the Tech 4 output for one of our models. It is a complicated model with a bifactor structure for one set of indicators (a general factor plus several group factors orthogonal to each other and the general factor) and a fairly simple unidimensional model for a second set of indicators (with a couple of correlated errors). Let's call the first set of indicators X and the second set Y. We want the correlations of each of the Y indicators with the X latent variables and whereas Tech 4 does show us the correlations of each of the X indicators with both the X and the Y latent variables, it doesn't show us the correlations of the Y indicators with the X latent variables. Any thoughts you might have would be most appreciated.

I can't get my head around this without seeing exactly what you are doing. Please send the full output and your license number to firstname.lastname@example.org.
I recently updated to Mplus version 7.11. The website indicates that p-values and standard errors for estimates of latent variable covariances are available with the Tech4 command in this new version. However, when I specified Tech4 in the Output section, all I saw were matrices of latent variable means, covariances, and correlations, no p-values or standard errors.
Example: "output: tech4;"
Is there something else I need to do to obtain p-values and standard errors? Does this option not work under certain conditions?
