A New Graphical Device and Related Tests for the Shape of Non-parametric Regression Function
Subhra Sankar Dhar, Prashant Jha, Mohammad Arshad Rahman +1
We consider a non-parametric regression model and propose a novel graphical device to check whether the -th () derivative of the regression functio…
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…
On Variable Screening in Multiple Nonparametric Regression Model
Subhra Sankar Dhar, Prashant Jha, Aranyak Acharyya
In this article, we study the problem of variable screening in multiple nonparametric regression model. The proposed methodology is based on the fact that the partial derivative of…
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…
A Test for Multivariate Location Parameter in Elliptical Model based on Forward Search Method
Chitradipa Chakraborty, Subhra Sankar Dhar
In this article, we develop a test for multivariate location parameter in elliptical model based on the forward search estimator for a specified scatter matrix. Here, we study the…
