This Fortran IV revision of an earlier three-mode factor analysis program uses a main program-subprogram structure and core storage and is written in a sufficiently general form as to be easily convertable to most machines having a Fortran IV compiler. (RC)

A Fortran IV program which computes either of the coefficients of congruence (psi or phi) used in comparison of factors in factor analysis is presented. Output consists of a non-symmetric matrix of factor coefficients. Listings of the program, results and test data are available. (Author/JKS)

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)

TMFA, a FORTRAN program for three-mode factor analysis and individual-differences multidimensional scaling, is described. Program features include a variety of input options, extensive preprocessing of input data, and several alternative methods of analysis. (Author)

The coefficient of congruence is a quantitative measure of the similarity of factor structures for different samples of subjects. This paper is intended to inform interested readers of the availability of a computer program capable of computing coefficients of congruence of factor structures. (Author)

A computer program to perform multiple-group factor analysis is presented. Written in Fortran Four, the program has a special feature to handle variables with strong negative correlations. (Author)

The Phi and G statistics for dichotomous variables are discussed and a Fortran program to compute them is described. Input is to be in card form, output may be printed, punched, or placed on magnetic tape. The punch or tape output is designed to be used as input for the BMD X72 factor analysis program. (Author)

A general factor analysis computer algorithm is briefly discussed. The algorithm is highly transportable with minimum limitations on the number of observations. Both singular and non-singular data can be analyzed. (Author/JKS)

A computer program to compare factor matrices which have at least some variables in common is described. The program calculates both the salient variable similarity index and the congruence coefficient. There are no limits for the number of variables or factors in either matrix. (Author/JKS)

Analytical comparisons are made of four commonly available packaged computer programs which perform principal-axis factor analysis. The four programs: Statistical Analysis System, Data-Text, Biomedical Computer Programs, and the Statistical Package for the Social Sciences were compared by running each program with the same data set.
