4S2 APPENDIX I visional estimates : they are shown under the heading of ' multi- pliers ' in the first column of Table II. 1. Insert the self-correlations, i.e. the squares of the estimated saturation coefficients (-81, -64, etc.), in the leading diagonal of the original table (Table I). 2. Multiply each row of correlations by the corresponding satura- tion coefficient (e.g. 1st row: -90 X -81 = -729, -90 X 72 = -648, I. SINGLE-FACTOR ANALYSIS fai A.
