Conditional Covariance Structure of Generalized Compensatory Multidimensional Items.
Zhang, Jinming; Stout, William
Psychometrika, v64 n2 p129-52 Jun 1999
Investigates the structure of item-pair conditional covariances given a unidimensional latent composite using a generalized semiparametric-modeling approach. Conditional covariances are shown to be highly informative about the latent dimensionality required to achieve local independence. Uses the new approach to justify the DIMTEST procedure. (SLD)
