I am running a LGM-model with 4 timepoints. I would like to add 1 time-invariant and 1 time-varying covariate to the growth trajectory. I am using TYPE=IMPUTATION for my analysis.
I know that when adding covariates the means of the growth factors are no longer printed but should be obtained from the TECH4 Output. I also read that Mplus 7.1 prints p-values for these latent variable means.
I am working with Mplus 7.11, but I cannot find the p-values. In fact, the output only prints means and covariance matrices. I tried working with only one of the imputed datasets, and then it also prints S.E.s and correlation matrices, but still no p-values.
Am I doing something wrong here? In addition, is there a way to obtain growth factor variances and their p-values as well?
