发帖数: 266 | 1 I used a simple program to calculate the communality and covariance matrix S
. And use the diagonal element of S, Sii-communality to get specific
variances. But sometimes the Sii
wrong for any reason?
Code:
proc factor data=test method=principal covariance;
run;
proc corr data=test cov;
var m100 m200 m400 m800 m1500 m3000 marathon;
run;
output for communality:
Variable Communality Weight
