Abstract : The generalized median of H. Oja yields a notion of bivariate quantile and in turn, an affine invariant bivariate analogue of the sign test. Its properties include a simple null covariance formula, facilitating a permutation or sign change test in the case of bivariate symmetry, normal efficiency coinciding with that of the Oja median, and bounded influence, hence strong robustness.
