Details
for 'modsem_lms', 'modsem_qml' and 'modsem_mplus' objects, the interaction term is not standardized such that var(xz) = 1. The interaction term is not an actual variable in the model, meaning that it does not have a variance. It must therefore be calculated from the other parameters in the model. Assuming normality and zero-means the variance is calculated as 'var(xz) = var(x) * var(z) + cov(x, z)^2'. Thus setting the variance of the interaction term to 1, would only be 'correct' if the correlation between x and z is zero. This means that the standardized estimates for the interaction term will be different from those using lavaan, since there the interaction term is an actual latent variable in the model, with a standardized variance of 1.
