Friedman, Sally; Weisberg, Herbert F.
Educational and Psychological Measurement, v41 n1 p11-21 Spr 1981
The first eigenvalue of a correlation matrix indicates the maximum amount of the variance of the variables which can be accounted for with a linear model by a single underlying factor. The first eigenvalue measures the primary cluster in the matrix, its number of variables and average correlation. (Author/RL)
