Abstract
Let x ∼ N(μ, Z), and let S = (Σ:μ). It is shown that if x′A1x is independent of x′Bx (x′A1x is distributed as a chi-square variable), then this property is inherited by every x′A2x for which S′A2S precedes S′A1S with respect to the range preordering (with respect to the rank subtractivity partial ordering). © 1984.
