Sets of Basic Programs for Factor Matrix Comparisons: Ahmavaara Transformation, Congruence Coefficient, Salient Variable Similarity Index
Ralph Mason Dreger · Educational and Psychological Measurement · 1985
BASIC programs for three different factor matrix comparison methods are described. Each method has several forms: Ahmavaara's procedure has one program for data entered as DATA, another for small matrices with data already stored on disk (or tape), another for large matrices with data already stored, and another for data already stored but with intermediate matrices not printed. The congruence coefficient programs include one for data entered as DATA, another for small matrices already stored, and another for large matrices already stored. Cattell's Salient Variable Similarity Index has one program with data entered as DATA, another for small matrices already stored, another for large matrices already stored, and another for large matrices already stored but with printing of the original matrices suppressed. Necessary microcomputer equipment is detailed. Input provisions and output expected are given.
