Structural equation modeling in epidemiology

Cadernos de Saúde Pública, 2010
Structural equation modeling (SEM) is an important statistical tool for evaluating complex relations in several research areas. In epidemiology, the use and discussion of SEM have been limited thus far. This article presents basic principles and concepts

Regularized Structural Equation Modeling [PDF]

Structural Equation Modeling, 2016
A new method is proposed that extends the use of regularization in both lasso and ridge regression to structural equation models. The method is termed regularized structural equation modeling (RegSEM). RegSEM penalizes specific parameters in structural equation models, with the goal of creating easier to understand and simpler models.

Analyzing Policy Capturing Data Using Structural Equation Modeling for Within-Subject Experiments (SEMWISE) [PDF]

Organizational Research Methods, 2019
We present the SEMWISE (structural equation modeling for within-subject experiments) approach for analyzing policy capturing data. Policy capturing entails estimating the weights (or utilities) of experimentally manipulated attributes in predicting a ...

Functional Structural Equation Model

Journal of the Royal Statistical Society Series B: Statistical Methodology, 2022
AbstractIn this article, we introduce a functional structural equation model for estimating directional relations from multivariate functional data. We decouple the estimation into two major steps: directional order determination and selection through sparse functional regression. We first propose a score function at the linear operator level, and show

Structural Equation Modeling

, 2017
Structural equation modeling (SEM) is a multivariate statistical framework that is used to model complex relationships between directly observed and indirectly observed (latent) variables. SEM is a general framework that involves simultaneously solving systems of linear equations and encompasses other techniques such as regression, factor analysis ...

Modeling alcohol use disorder severity: An integrative structural equation modeling approach [PDF]

, 2013
Background: Alcohol dependence is a complex psychological disorder whose phenomenology changes as the disorder progresses. Neuroscience has provided a variety of theories and evidence for the development, maintenance, and severity of addiction; however ...

Products of Variables in Structural Equation Models

Structural Equation Modeling: A Multidisciplinary Journal, 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).
