✦ Synopsis

ten Berge (Comput. Statist. Data Anal. 24, 1997, 357-366) distinguished between rank-one and rank-two departures from symmetry. A re-examination suggests that there is no substantive di erence between the two approaches unless the type of symmetry is constrained in some way. The relationship between rank and dimensionality in the context of asymmetry is clariΓΏed. Implications for diagnostic methods for distinguishing between di erent models of asymmetry are discussed, paying special attention to additive adjustments to a distance matrix.

O what a tangled web we weave when ΓΏrst we practise to deceive. (Sir Walter Scott, Marmion). There's no such thing as a free lunch. (Well-known saying).
