Theoretical guarantees for change localization using conformal p-values
Swapnaneel Bhattacharyya, Aaditya Ramdas
Changepoint localization aims to provide confidence sets for a changepoint (if one exists). Existing methods either relying on strong parametric assumptions or providing only asymp…
Testing Equality of Medians for Multiple Samples
Swapnaneel Bhattacharyya
In this paper, we construct a consistent non-parametric test for testing the equality of population medians for different samples when the observations in each sample are independe…
Application of Random Matrix Theory in High-Dimensional Statistics
Swapnaneel Bhattacharyya, Srijan Chattopadhyay, Sevantee Basu
This review article provides an overview of random matrix theory (RMT) with a focus on its growing impact on the formulation and inference of statistical models and methodologies.…
Analysis of Pleiotropy for Testosterone and Lipid Profiles in Males and Females
Srijan Chattopadhyay, Swapnaneel Bhattacharyya, Sevantee Basu
In modern scientific studies, it is often imperative to determine whether a set of phenotypes is affected by a single factor. If such an influence is identified, it becomes essenti…
A Statistical Approach to Ecological Modeling by a New Similarity Index
Srijan Chattopadhyay, Swapnaneel Bhattacharyya
Similarity index is an important scientific tool frequently used to determine whether different pairs of entities are similar with respect to some prefixed characteristics. Some st…
