A Program for Oblique and Orthogonal Procrustes Rotation.
PDF on ERIC Download full text
Jensema, Carl; Urry, Vern W. – 1971
Procrustes rotation involves fitting a factor pattern matrix to a specified target matrix in factor analysis. These rotations are useful for the investigator who wishes to see how well his data can be made to fit a hypothesized factor pattern matrix. The mathematical problems involved in these transformations are outlined and computer algorithms…

On Various Causes of Improper Solutions in Maximum Likelihood Factor Analysis
Peer reviewed Peer reviewed
van Driel, Otto P. – Psychometrika, 1978
In maximum likelihood factor analysis, there arises a situation whereby improper solutions occur. The causes of those improper solution are discussed and illustrated. (JKS)

Fitting Nonmetric Scaling Solutions to Hypothesized Targets
Peer reviewed Peer reviewed
Carroll, Robert M.; And Others – Educational and Psychological Measurement, 1972
A copy of the computer program, which determines the transformation matrix used to rotate the configuration, the dilation factor, and the translation vector, is available from the first author. (CB)

Factor Analysis of Dichotomized Variables
Peer reviewed Peer reviewed
Christoffersson, Anders – Psychometrika, 1975
An approach for multiple factor analysis of dichotomized variables is presented based on distribution of first and second order joint probabilities of binary scored items. The estimator is based on the generalized least squares principle. Standard errors and a test of the fit of the model is given. (Author/RC)

Bibliography of Papers on Latent Trait Assessment.
Cohen, Allan S., Comp. – 1979
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annotated bibliography of journal articles, dissertations, convention papers, research reports, and a few books and unpublished manuscripts provides a comprehensive coverage of work on latent trait theory and practice.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.…
