چکیده
Description Extended Structural Equation Modelling (SEM). Models may be specified with reticular action model (RAM) matrices or paths,linear structural relations (LISREL) matrices or paths, or directly in matrix algebra. To increase modularity, model expectations,fit functions, and optimizers can be easily interchanged. Fit functions include full information maximum likelihood (FIML),maximum likelihood (ML), and weighted least squares (WLS). Possible models include confirmatory factor, multiple group, mixture distribution, categorical threshold, modern test theory, differential equations, state space, and many others.

متن کاملOpenMx 2.0: Extended Structural Equation and Statistical Modeling.
The new software package OpenMx 2.0 for structural equation and other statistical modeling is introduced and its features are described. OpenMx is evolving in a modular direction and now allows a mix-and-match computational approach that separates model expectations from fit functions and optimizers. Major backend architectural improvements include a move to swappable open-source optimizers suc...
متن کاملModel Builder for Item Factor Analysis with OpenMx
We introduce a shiny web application to facilitate the construction of Item Factor Analysis (a.k.a. Item Response Theory) models using the OpenMx package. The web application assists with importing data, outcome recoding, and model specification. However, the app does not conduct any analysis but, rather, generates an analysis script. Generated Rmarkdown output serves dual purposes: to analyze ...
متن کاملNonlinear Structured Growth Mixture Models in Mplus and OpenMx.
Growth mixture models (GMMs; Muthén & Muthén, 2000; Muthén & Shedden, 1999) are a combination of latent curve models (LCMs) and finite mixture models to examine the existence of latent classes that follow distinct developmental patterns. GMMs are often fit with linear, latent basis, multiphase, or polynomial change models because of their common use, flexibility in modeling many types of change...
متن کاملExtraction of the Longitudinal Movement of the Carotid Artery Wall using Consecutive Ultrasonic Images: a Block Matching Algorithm
Introduction: In this study, a computer analysis method based on a block matching algorithm is presented to extract the longitudinal movement of the carotid artery wall using consecutive ultrasonic images. A window (block) is selected as the reference block in the first frame and the most similar block to the reference one is found in the subsequent frames. Material and Methods: The program was...
