Abstract: For normal linear experiments and with unknown variance components [sigma]i, I = 1,...,q, we consider some relations of type "1 is at least as good as 2", among others with respect to (a) linear estimation, (b) quadratic estimation and (c) quadratic estimation of variance components. It is shown, in a simple way, that (b)=>(c)=>(a).
