  ABSTRACT: Optimization has two faces, minimization of a loss function or maximization of a gain function. We show that the mean absolute deviation about the mean, d, maximizes a gain function based on the power set of the individuals; and nd, where nis the sample size, equals twice the value of the cut-norm of the deviations about the mean. This property is generalized to double-centered and triple-centered data sets. Furthermore, we show that among the three well known dispersion measures, standard deviation, least absolute deviation and d, dis the most robust based on the relative contribution criterion. More importantly, we show that the computation of each principal dimension of taxicab correspondence analysis (TCA) corresponds to balanced 2-blocks seriation. These ideas are applied on two data sets.
