Implications of a Class of Covariance Structure Models for the Development of Measuring Instruments.
Bramble, William J.; Wiley, David E.
The research on covariance structure analysis is reviewed, and various restrictions on the parameter matrices of the general model are delineated. Models employing two particular restrictions (where the matrix of weights is completely specified and is either scaled--by some unknown but estimable matrix of scaling weights--or unscaled) are discussed in particular, and their application to test development techniques is considered. It is suggested that more precise measuring instruments can be developed through these procedures by studying the characteristics of the test and the test items, the latent variables, and the ensuing relationships. An example is provided. A computer program for solving likelihood equations and for testing fit is available. (GS)
