A Hybrid Symbolic/Numeric Solution To Polynomial SEM

  title={A Hybrid Symbolic/Numeric Solution To Polynomial SEM},
  author={Reinhard Oldenburg},
There are many approaches to nonlinear SEM (structural equation modeling) but it seems that a rather straightforward approach using Isserlis’ theorem has not yet been investigated although it allows the direct extension of the standard linear approach to nonlinear linear SEM. The reason may be that this method requires some symbolic calculations done at runtime. This paper describes the class of appropriate models and outlines the algorithm that calculates the covariance matrix and higher… Expand

Fitting Nonlinear Structural Equation Models in R with Package nlsem
Structural equation mixture modeling (SEMM) has become a standard procedure in latent variable modeling over the last two decades (Jedidi, Jagpal, and DeSarbo'97b; Muthen and Shedden'99; Muthen 2001,Expand
Estimation of nonlinear latent structural equation models using the extended unconstrained approach
Numerous theories within the social and behavioral sci-ences hypothesize interaction, quadratic effects, or both between multiple independent and dependent variables (Ajzen, 1987; Cronbach & Snow,Expand
A comparison of methods for estimating quadratic effects in nonlinear structural equation models.
Of the 5 estimation methods, it was found that overall the methods based on maximum likelihood estimation and the Bayesian approach performed best in terms of bias, root-mean-square error, standard error ratios, power, and Type I error control, although key differences were observed. Expand
Advanced Nonlinear Latent Variable Modeling: Distribution Analytic LMS and QML Estimators of Interaction and Quadratic Effects
Interaction and quadratic effects in latent variable models have to date only rarely been tested in practice. Traditional product indicator approaches need to create product indicators (e.g., x 1 2,Expand
