SEM multigroup modeling
Hello,
I am using the SEM package in R to fit a multigroup latent variable model and ran into some difficulties. I have 2 questions:
1. First, I am getting the following error message and wondering what to do to fix it:
Error in solve.default((N[g] - 1) * robustVcov(mod.g, adj.obj = adj.objects[[g]])) :
system is computationally singular: reciprocal condition number = 4.52055e-23
2. Second, I want to specify different models for two groups (Drivers vs. Nondrivers), but I want only 1 parameter to be different, while everything else remains the same....
