Factor Analysis of the Image Correlation Matrix

Abstract

The factor analysis of the image correlation matrix is suggested. Whether to factor the image correlation matrix itself or to proceed via a new model with an alpha (common) factor analysis of it is mentioned, with particular reference to the determinacy problem. The transformation (rotation) problem, in the oblique case, has a new aspect, for which a tentative resolution is proposed. It is pointed out that the distribution of the images is sensibly multivariate normal, making for "better" factor analyses.
