Fast high-dimensional mean testing via logistic regression
Sayan Das, Debraj Das, Subhajit Dutta
We propose computationally efficient tests for equality of mean vectors of two or more high-dimensional populations. Central to our approach is an equivalence between equality of m…
Uniform-over-dimension location tests for multivariate and high-dimensional data
Ritabrata Karmakar, Joydeep Chowdhury, Subhajit Dutta +1
Asymptotic methods for hypothesis testing in high-dimensional data usually require the dimension of the observations to increase to infinity, often with an additional relationship…
Uniform-over-dimension convergence with application to location tests for high-dimensional data
Joydeep Chowdhury, Subhajit Dutta, Marc G. Genton
Asymptotic methods for hypothesis testing in high-dimensional data usually require the dimension of the observations to increase to infinity, often with an additional condition on…
Robust Classification of High-Dimensional Data using Data-Adaptive Energy Distance
Jyotishka Ray Choudhury, Aytijhya Saha, Sarbojit Roy +1
Classification of high-dimensional low sample size (HDLSS) data poses a challenge in a variety of real-world situations, such as gene expression studies, cancer research, and medic…
On Exact Feature Screening in Ultrahigh-dimensional Binary Classification
Sarbojit Roy, Soham Sarkar, Subhajit Dutta +1
We propose a new model-free feature screening method based on energy distances for ultrahigh-dimensional binary classification problems. With a high probability, the proposed metho…
Sub-dimensional Mardia measures of multivariate skewness and kurtosis
Joydeep Chowdhury, Subhajit Dutta, Reinaldo B. Arellano-Valle +1
The Mardia measures of multivariate skewness and kurtosis summarize the respective characteristics of a multivariate distribution with two numbers. However, these measures do not r…
