Extreme Geometric Quantiles Under Minimal Assumptions, with a Connection to Tukey Depth

Sibsankar Singha, Marie Kratz, Sreekar Vadlamani

Geometric (also known as spatial) quantiles, introduced by Chaudhury and representing one of the three principal approaches to defining multivariate quantiles, have been well studi…

Discriminating Tail Behavior Using Halfspace Depths: Population and Empirical Perspectives

Sibsankar Singha, Marie Kratz, Sreekar Vadlamani

We study the empirical version of halfspace depths with the objective of establishing a connection between the rates of convergence and the tail behaviour of the corresponding unde…

Comparing Multivariate Distributions: A Novel Approach Using Optimal Transport-based Plots

Sibsankar Singha, Marie Kratz, Sreekar Vadlamani

Quantile-Quantile (Q-Q) plots are widely used for assessing the distributional similarity between two datasets. Traditionally, Q-Q plots are constructed for univariate distribution…

Extremal behaviour and convergence rates for sample--based geometric quantiles and half space depths

Sibsankar Singha, Marie Kratz, Sreekar Vadlamani

We consider the empirical versions of geometric quantile and halfspace depth, and study their extremal behaviour as a function of the sample size. The objective of this study is to…

Asymptotic Properties of Linear Filter for Noise Free Dynamical System

Anugu Sumith Reddy, Amit Apte, Sreekar Vadlamani

It is known that Kalman-Bucy filter is stable with respect to initial conditions under the conditions of uniform complete controllability and uniform complete observability (Bishop…

Spatio-temporal Patterns of Indian Monsoon Rainfall

Adway Mitra, Amit Apte, Rama Govindarajan +2

The primary objective of this paper is to analyze a set of canonical spatial patterns that approximate the daily rainfall across the Indian region, as identified in the companion p…
