Two Computer Programs for Factor Analysis. Technical Note Number 41.
Wisler, Carl E.
Two factor analysis algorithms, previously described by P. Horst, have been programed for use on the General Electric Time-Sharing Computer System. The first of these, Principal Components Analysis (PCA), uses the Basic Structure Successive Factor Method With Residual Matrices algorithm to obtain the principal component vectors of a correlation matrix. The program will accept up to fifty variables in the correlation matrix and will successively compute up to thirty component vectors; it terminates upon finding a latent root less than one. Varimax Rotation (VARR) uses the Successive Factor Varimax Solution algorithm to produce a normalized rotated factor matrix, given no more than 10 principal component vectors of up to 50 variables. FORTRAN listings and sample runs of both programs are appended. (RM)
