Stochastic Approximation for Multivariate and Functional Median

2010
We propose a very simple algorithm in order to estimate the geometric median, also called spatial median, of multivariate (Small (1990)) or functional data (Gervini (2008)) when the sample size is large. A simple and fast iterative approach based on the Robbins-Monro algorithm (Duflo (1997)) as well as its averaged version (Polyak and Juditsky (1992 ...

A note on the multivariate multisample rank sum and median tests

Communications in Statistics - Theory and Methods, 1986
The muitivariate nonparametric tests analogous to the univar-iate rank sum test and median test are contained in Puri and Sen (1970). These tests provided a practical alternative for the analysis of multivariate data when the assumptions of parametric methods are not satisfied. In this paper maximum values for LNthe asymptotic chi-Square test statistic

Some extension of Haldane's multivariate median and its application

Annals of the Institute of Statistical Mathematics, 1985
For X p-dimensional with expectation \(\mu\) and covariance matrix \(\Sigma\), \textit{J. B. S. Haldane}'s [Biometrika 35, 414-415 (1948; Zbl 0032.03601)] definition of a multivariate median as a minimizer \(\theta_ 0\) of \(E\| X-\theta \|\), where \(\| X-\theta\| = \{(X-\theta)'\Sigma^{-1}(X-\theta)\}^{1/2},\) is considered.
