measurement invariance with theta and lisrel parameterization
I’m trying to test a model of threshold invariance for ordinal indicators across 6 time points using semTools::measEq.syntax() with
parameterization = "theta",
ID.cat = "...

Strange pattern of fit indices in Measurement invariance testing
I am testing measurement invariance across 7 time points using WLSMV since my indicators are ordinal. Here are my results:
When I impose threshold constraints, the overall fit indices get worse (...

Autoregressive Latent Trajectory with Structured Residuals
I'm trying to estimate an ALT-SR model (autoregressive latent trajectory with random intercepts) where stress is continuous and smoke is ordinal (0/1).
When I run the model I get the following warning:...

CFA multiple multi-item scales
In my survey, I measured two variables:
Dependent variable: 1 factor of a construct consisting of 4 factors (measured by 4 items each); all factors were measured to maybe conduct additional analyses ...
