This article presents relevant research on Bayesian methods and their major applications to modeling in an effort to lay out differences between the frequentist and Bayesian paradigms and to look at the practical implications of these differences. Before research is reviewed, basic tenets and methods of the Bayesian approach to modeling are…

Outlines a covariance structure analysis approach to the study of parameter trends. Uses the program RAMONA to illustrate the method by fitting a corresponding confirmatory factor analysis model to correlational data from a study involving several psychometric tests and fluid intelligence tasks. (SLD)

Teachers are advised that analysis of covariance structures can be used to obtain estimates of variance components for use in generalizability analyses. Generalizability theory provides a flexible and practical framework for examining the psychometric properties of testing situations. This article illustrates the approach for fully crossed…

Evaluated the psychometric properties of a perceptual measure of the extent to which manufacturing organizations develop proprietary equipment, the Proprietary Equipment Scale (developed by the World Class Manufacturing study). Analysis of data from 164 manufacturing plants in 5 countries indicates that although method effects are present, the…
