Covariance matrix(S)–>In diagonal it have variances (spread) and in off-daigonal covariances (pos and orientation). Measure the linera dependency between observations of each pair of vars. Its rank determines the number of linearly independent variables in the data matrix and it is also the number of eigenvalues different from 0. >varaince — >spread — <>Generalizated variance (|S|)–> When |S|=0 there are some variables that are linear combinations of the others.
