An Incomplete Data Approach to the Analysis of Covariance Structures.

Peer reviewed

Kiiveri, H. T. – Psychometrika, 1987

Covariance structures associated with linear structural equation models are discussed. Algorithms for computing maximum likelihood estimates (namely, the EM algorithm) are reviewed. An example of using likelihood ratio tests based on complete and incomplete data to improve the fit of a model is given. (SLD)
