Application of the EM Method A Study of Maximum Likelihood Estimation of Multiple Indicator and Factor Analysis Models

TLDR
The EM (Estimation-Maximization) algorithm is exploited to provide maximum likelihood estimates of the parameters of multiple indicator/factor analysis models to reduce considerably the storage and computational burden of such estimation.
Abstract
The EM (Estimation-Maximization) algorithm is exploited to provide maximum likelihood estimates of the parameters of multiple indicator/factor analysis models. This method reduces considerably the storage and computational burden of such estimation. A computer program in BASIC language that performs the computations is listed in an appendix. The specification of correlated errors is also provided for in this application of the method.

Discovery and representation of causal relationships in MIS research: a methodological framework

TL;DR: The paper describes the representational shortcomings and statistical pitfalls of factor-analytic methods commonly deployed in empirical research and proposes using TETRAD, a non-parametric tool, at the exploratory phase for its ability to accommodate a wide variety of causal models.

Uniqueness does not Imply Identification A Note on Confirmatory Factor Analysis

TL;DR: This paper showed that conditions originally presented by Howe (1955) and later by Joreskog (1979) are not sufficient to identify confirmatory factor analysis models, and showed that these conditions are insufficient.

A general method for analysis of covariance structures

Karl G. Jöreskog
- 01 Aug 1970 - 
TL;DR: In this article, a general multivariate normal distribution with a general parametric form of the mean vector and the variance-covariance matrix is proposed, where any parameter of the model may be fixed, free or constrained to be equal to other parameters.

EM Algorithms for ML Factor Analysis.

TL;DR: In this paper, the authors present EM algorithms for both exploratory and confirmatory models for maximum likelihood factor analysis, which are essentially the same for both cases and involve only simple least squares regression operations; the largest matrix inversion required is for aq ×q symmetric matrix whereq is the matrix of factors.

Linear structural equations with latent variables

TL;DR: In this article, an interdependent multivariate linear relations model based on manifest, measured variables as well as unmeasured and unmeasurable latent variables is developed, which is designed to accommodate a wider range of applications via its structural equations, mean structure, covariance structure, and constraints on parameters.
