A Smooth Nonparametric, Multivariate, Mixed-Data Location-Scale Test [PDF]
SSRN Electronic Journal, 2017 A number of tests have been proposed for assessing the location-scale assumption that is often invoked by practitioners. Existing approaches include Kolmogorov–Smirnov and Cramer–von Mises statistics that each involve measures of divergence between unknown joint distribution functions and products of marginal distributions.

Minimax bounds for estimating multivariate Gaussian location mixtures [PDF]
Electronic Journal of Statistics, 2022 We prove minimax bounds for estimating Gaussian location mixtures on $\mathbb{R}^d$ under the squared $L^2$ and the squared Hellinger loss functions. Under the squared $L^2$ loss, we prove that the minimax rate is upper and lower bounded by a constant multiple of $n^{-1}(\log n)^{d/2}$. Under the squared Hellinger loss, we consider two subclasses based

A New Nonparametric Test for Two Sample Multivariate Location Problem with Application to Astronomy
Journal of Statistical Theory and Applications (JSTA), 2019 This paper provides a nonparametric test for the identity of two multivariate continuous distribution functions when they differ in locations. The test uses Wilcoxon rank-sum statistics on distances between observations for each of the components and is ...

Scientific Reports, 2022 The etiology of open-angle glaucoma (OAG) is yet unclear. This study investigated possible risk factors, such as the morphology of the border tissue that affect the pattern of visual field (VF) progression in eyes with OAG.

On Some Shrinkage Estimators of Multivariate Location
The Annals of Statistics, 1985 Let \(F_{\theta}\) be a p (\(\geq 1)\) variate continuous distribution function (d.f.) defined on the Euclidean space \(E^ p\). The d.f. \(F_{\theta}\) is assumed to be diagonally symmetric about its location \(\theta =(\theta_ 1,...,\theta_ p)^ T\). In a shrinkage estimation problem, one has, a priori, some reason to believe that \(\theta\) is likely ...

Computing the Oja Median in R: The Package OjaNP
Journal of Statistical Software, 2020 The Oja median is one of several extensions of the univariate median to the multivariate case. It has many desirable properties, but is computationally demanding.
