On the optimality of antithetic randomization for cross-validation
Srijan Chattopadhyay, Sifan Liu, Snigdha Panigrahi
In the classical normal means problem, independent train--test folds can be constructed by perturbing the data with normal randomization. Averaging over such folds yields a cro…
Inference for quantile-parametrized families via CDF confidence bands
Srijan Chattopadhyay, Siddhaarth Sarkar, Arun Kumar Kuchibhotla
Quantile-based distribution families are an important subclass of parametric families, capable of exhibiting a wide range of behaviors using very few parameters. These parametric m…
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…
