compare_fit: compare model fit for qml and lms models

In modsem: Latent Interaction (and Moderation) Analysis in Structural Equation Models (SEM)

compare model fit for qml and lms models

Description

Compare the fit of two models using the likelihood ratio test. 'estH0' representing the null hypothesis model, and 'estH1' the alternative hypothesis model. Importantly, the function assumes that 'estH0' does not have more free parameters (i.e., degrees of freedom) than 'estH1'. alternative hypothesis model

Usage

compare_fit(estH0, estH1)

Arguments

estH0	object of class 'modsem_da' representing the null hypothesis model
estH1	object of class 'modsem_da' representing the
