compare_fit: 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
