While many readers may be unfamiliar with the full complexity of the covariance structure model, many may have mastered at least one of its two components each of which is a powerful and wellknown statistical technique in its own right. The first is the confirmatory factor model frequently used in psychometrics; the second, the structural equation model, is familiar to econometricians. The discussion in this volume will be particularly useful for estimating models with equality constraints and correlated errors across some but not all equations. The final chapter includes a guide to appropriate software packages.
