Thus \(\det A<0\) if and only if the two eigenvalues are nonzero and have opposite signs (making \(A\) indefinite). \(\det A>0\) if and only if the two eigenvalues are nonzero and have the same sign. damira tomljanovića gavrana 15WebHi, I was trying to calculate the CCC metric in R with the help of "NbClust" source code and the available SAS manual for CCC.
