Some Further Notes on the Problem of Oblique Factor Transformation.
Hakstian, A. Ralph; Abell, Robert A.
Four prominent oblique transformation techniques--biquartimin, direct oblimin, promax, and the Harris-Kaiser procedure--are described and compared as to optimality of solution. Additionally, two newly-developed procedures--falling into the category designated as Case III by Harris and Kaiser (1964)--are presented and included in the comparisons. The techniques are compared in light of their ability to yield clear simple structures over many data sets--some constructed and some "real"--varying widely in terms of number of variables and factors, factorial complexity, and clarity of the hyperplanes. Results indicate that no single computing procedure can be counted on to be uniformly optimal for all kinds of data. Also, there appear to be complicated interactions between the specification parameter and various characteristics of the data. The two new procedures yielded encouraging results. (Author/CTM)
