Title: A Marginal Maximum Likelihood Approach for Extended Quadratic Structural Equation Modeling
Abstract: The literature on non-linear structural equation modeling is plentiful. Despite this fact, few studies consider interactions between exogenous and endogenous latent variables. A marginal maximum likelihood-based approach is proposed in order to fit a non-linear structural equation model including interactions between exogenous and endogenous latent variables. In this approach the exact gradient of the approximated observed log likelihood is calculated, which is computationally more efficient than the EM algorithm. A simulation study shows that the proposed method provides estimates with low bias and accurate coverage probabilities.
