Co-variance Operator of Banach Valued Random Elements: U-Statistic Approach
Suprio Bhar, Subhra Sankar Dhar
This article proposes a co-variance operator for Banach valued random elements using the concept of -statistic. We then study the asymptotic distribution of the proposed co-vari…
Testing Independence of Infinite Dimensional Random Elements: A Sup-norm Approach
Suprio Bhar, Subhra Sankar Dhar
In this article, we study the test for independence of two random elements and lying in an infinite dimensional space (specifically, a real separable Hilbert sp…
The Trimmed Mean in Non-parametric Regression Function Estimation
Subhra Sankar Dhar, Prashant Jha, Prabrisha Rakhshit
This article studies a trimmed version of the Nadaraya-Watson estimator to estimate the unknown non-parametric regression function. The characterization of the estimator through mi…
Identifying shifts between two regression curves
Holger Dette, Subhra Sankar Dhar, Weichi Wu
This article studies the problem whether two convex (concave) regression functions modelling the relation between a response and covariate in two samples differ by a shift in the h…
Comparison of multivariate distributions using quantile-quantile plots and related tests
Subhra Sankar Dhar, Biman Chakraborty, Probal Chaudhuri
The univariate quantile-quantile (Q-Q) plot is a well-known graphical tool for examining whether two data sets are generated from the same distribution or not. It is also used to d…
