Testing Microbiome Community Differences in High Dimensions: A Bootstrap Approach for Compositional Data
Monika Bhattacharjee, Nilanjan Chakraborty, Sayan Das +6
Understanding differences in microbial community structure is critical for uncovering risk factors and mechanisms underlying diseases such as colorectal cancer and preterm birth. M…
Limiting Spectral Distribution of moderately large Kendall's correlation matrix and its application
Raunak Shevade, Monika Bhattacharjee
We establish the limiting spectral distribution of Kendall's correlation matrices in the moderate high-dimensional regime where the dimension grows slower than the sample size. Our…
Joint convergence of sample cross-covariance matrices
Monika Bhattacharjee, Arup Bose, Apratim Dey
Suppose and are matrices each with mean , variance and where all moments of any order are uniformly bounded as . Moreover, the entries $(…
Asymptotic freeness of sample covariance matrices via embedding
Monika Bhattacharjee, Arup Bose
We present an alternative proof of asymptotic freeness of independent sample covariance matrices, when the dimension and the sample size grow at the same rate, by embedding these m…
Change Point Estimation in Panel Data with Temporal and Cross-sectional Dependence
Monika Bhattacharjee, Moulinath Banerjee, George Michailidis
We study the problem of detecting a common change point in large panel data based on a mean shift model, wherein the errors exhibit both temporal and cross-sectional dependence. A…
Change Point Estimation in a Dynamic Stochastic Block Model
Monika Bhattacharjee, Moulinath Banerjee, George Michailidis
We consider the problem of estimating the location of a single change point in a dynamic stochastic block model. We propose two methods of estimating the change point, together wit…
