Generalized M-Estimation in Censored Regression Model under Endogeneity
Swati Shukla, Subhra Sankar Dhar, Shalabh
We propose and study M-estimation to estimate the parameters in the censored regression model in the presence of endogeneity, i.e., the Tobit model. In the course of this study, we…
A novel characterization of structures in smooth regression curves: from a viewpoint of persistent homology
Satish Kumar, Subhra Sankar Dhar
We characterize structures such as monotonicity, convexity, and modality in smooth regression curves using persistent homology. Persistent homology is a key tool in topological dat…
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…
Inspecting discrepancy between multivariate distributions using half-space depth based information criteria
Pratim Guha Niyogi, Subhra Sankar Dhar
This article inspects whether a multivariate distribution is different from a specified distribution or not, and it also tests the equality of two multivariate distributions. In th…
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…
