A Fortran IV program is presented which will cross-correlate least squares estimated factor scores across separately factor analyzed variable domains without the tedious necessity of actually calculating the factor scores. (RC)

Several advantages to the use of different kinds of factor scores as independent variables in a multiple regression equation are reported. A computer program is presented which will calculate a regression equation using a variety of factor scores. (Author/JKS)

A major problem in the research concerning distributional and other properties of reliability coefficients has been the non-existence or inaccessibility of adequate test data for use in empirical verification of hypothetical conclusions. The purpose of this paper is to develop a technique for the simulation of test item scores through the use of…

Technical improvements, which may be made in the reliability and validity of tests through confidence scores, are discussed. However, studies indicate that subjects do not handle their confidence uniformly. (MS)

This partially annotated bibliography of journal articles, dissertations, convention papers, research reports, and a few books and unpublished manuscripts provides a comprehensive coverage of work on latent trait theory and practice. Documents are arranged alphabetically by author. The period covered ranges from the early 1950's to the present.…
