Estimating Local Structural Equation Models [PDF]

open access: yesJournal of Intelligence, 2023
Local structural equation models (LSEM) are structural equation models that study model parameters as a function of a moderator. This article reviews and extends LSEM estimation methods and discusses the implementation in the R package sirt.

Products of Variables in Structural Equation Models. [PDF]

open access: yesStruct Equ Modeling, 2023
A general method is introduced in which variables that are products of other variables in the context of a structural equation model (SEM) can be decomposed into the sources of variance due to the multiplicands. The result is a new category of SEM which we call a Products of Variables Model (PoV).

Choice Function-Based Hyper-Heuristics for Causal Discovery under Linear Structural Equation Models [PDF]

open access: yesBiomimetics
Causal discovery is central to human cognition, and learning directed acyclic graphs (DAGs) is its foundation. Recently, many nature-inspired meta-heuristic optimization algorithms have been proposed to serve as the basis for DAG learning.

General guidance for custom-built structural equation models [PDF]

open access: yesOne Ecosystem, 2022
Structural Equation Modelling (SEM) represents a quantitative methodology for specifying and evaluating causal network hypotheses. The application of SEM typically involves the use of specialised software packages that implement estimation procedures and

Modeling Model Misspecification in Structural Equation Models

open access: yesStats, 2023
Structural equation models constrain mean vectors and covariance matrices and are frequently applied in the social sciences. Frequently, the structural equation model is misspecified to some extent.

Implementation Aspects in Regularized Structural Equation Models

open access: yesAlgorithms, 2023
This article reviews several implementation aspects in estimating regularized single-group and multiple-group structural equation models (SEM). It is demonstrated that approximate estimation approaches that rely on a differentiable approximation of non ...

Model-Robust Estimation of Multiple-Group Structural Equation Models

open access: yesAlgorithms, 2023
Structural equation models (SEM) are widely used in the social sciences. They model the relationships between latent variables in structural models, while defining the latent variables by observed variables in measurement models.

Hierarchical Structural Analysis Method for Complex Equation-Oriented Models

open access: yesMathematics, 2021
Structural analysis is a method for verifying equation-oriented models in the design of industrial systems. Existing structural analysis methods need flattening of the hierarchical models into an equation system for analysis.
