Factor indeterminacy: The saga continues
William W. Rozeboom · British Journal of Mathematical and Statistical Psychology · 1988
The much‐discussed prevailing failure of a moment decomposition M zz = AM 0 A to identify just one factor tuple F such that Z = AF and M FF = M 0 is only one of many ways in which a selected fragment of a complete factor solution generally specifies the solution's remainder only imperfectly. Precise ranges are worked out here for the main varieties of such indeterminacies, together with the special conditions, if any, under which they shrink to unique determinations.
