When I replicated the example in factor analysis, the result confirms the output in page 724 of User guide II. However, for the summary information on the total variance and proportion of common variance, I am puzzled with the resuld
1 the "Cumulative" column, how to explain the total cumulative? see the 3rd line of the text, the cumulative variance accounted for by the two factors is 3.546949, not 6.27 (6.266613), only 50% (not 90%) of the total variance.
2 the "Proportion" column, gives the proportion within the factors, not for total variance from observed variance/correlation matrix. It is much informative to report the proportion of total sample variance due to each of the factors
