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…
Classic dynamic fracture recovered as the limit of a nonlocal peridynamic model: The single edge notch in tension
Robert Lipton, Prashant K. Jha
A simple nonlocal field theory of peridynamic type is applied to model brittle fracture. The fracture evolution is shown to converge in the limit of vanishing nonlocality to classi…
Finite element convergence for state-based peridynamic fracture models
Prashant K. Jha, Robert Lipton
We establish the a-priori convergence rate for finite element approximations of a class of nonlocal nonlinear fracture models. We consider state based peridynamic models where the…
