umx: Twin and Path-based Structural Equation Modeling in OpenMx

Structural equation modeling (SEM) is an important research tool, especially in the social sciences. Two major uses of SEM include path-based model specification, where ease of use and graphical and table-based reporting are important for researcher productivity, and complex multi-group and multi-level models developed in fields such as behavior genetics where the model specification might ofte...

Structural Equation Modeling/Path Analysis

Path Analysis is the statistical technique used to examine causal relationships between two or more variables. It is based upon a linear equation system and was first developed by Sewall Wright in the 1930s for use in phylogenetic studies. Path Analysis was adopted by the social sciences in the 1960s and has been used with increasing frequency in the ecological literature since the 1970s. In ec...

Path analysis of occupational injuries based on the structural equation modeling approach: a retrospective study in the construction industry

Background and aims: The construction industry, sites, and projects are the most dangerous industries in terms of the risk of occupational accidents and injuries. Important factors that have led the industry as a health, safety, environment (HSE) high-risk industry in the world can be cited such as continuous changes in construction projects, using a lot of resources, poor working conditions,...

Structural Equation Modeling With the sem Package in R

R is free, open-source, cooperatively developed software that implements the S statistical programming language and computing environment. The current capabilities of R are extensive, and it is in wide use, especially among statisticians. The sem package provides basic structural equation modeling facilities in R, including the ability to fit structural equations in observed variable models by ...

Continuous Time Structural Equation Modeling with R Package ctsem

We introduce ctsem, an R package for continuous time structural equation modeling of panel (N > 1) and time series (N = 1) data, using full information maximum likelihood. Most dynamic models (e.g., cross-lagged panel models) in the social and behavioural sciences are discrete time models. An assumption of discrete time models is that time intervals between measurements are equal, and that all ...
