Variances and Covariances
Correlations are obtained by checking the "
" button. For the above example we have
Rweb:> cor(variables) Height Weight Height 1.000000 0.780414 Weight 0.780414 1.000000
The diagonal elements are always 1. The correlations are the off-diagonal elements. In this case the correlation between "Height" and "Weight" is 0.780414.
