Webballows the use of ranked data in this special form of general linear hypothesis (Shirley, 1981). However, alternative uses of ranks in analysis of covariance can be proposed and … WebbThe rank of centered data becomes min (n, m − 1), because each data row is now subjected to constraint: ∑mi = 1z ∗ i = 0. It basically means we can recreate the entire z matrix even if one of columns is removed. The equation for sample covariance of x becomes: cov(x, x) = 1 m − 1zzT Clearly, the rank of covariance matrix is the rank(zzT).
