An expository article on goodness of fit and model choice for covariance structure models for psychologists. Discussion of sample sizes, practical and statistical significance, choice of the null model, de-emphasising significance tests. Steiger et al.
Simulation suggests that formulas work well in reasonably large samples.
Essentially a generalised R2 for a GLS estimate of the covariance matrix. Discusses indices of fit. Saris et al. Suggest a statistic which measures changes in each of the parameters when restrictions on them are lifted. Marsh et al.
