Remarks on tucker's inter-battery method of factor analysis

Tucker's inter-battery method of factor analysis is shown to assume implicitly that, within the factor space of overlap between the vector configurations of the two test batteries involved, the locations of the two sets of principal axes and the sizes of the associated characteristic roots are identical. A suggested modification of the inter-battery method to avoid these restrictions is considered.The opinions expressed are those of the author and are not to be construed as reflecting official Department of Army policy.
