Inference for Projection Parameters in Linear Regression: beyond
Woonyoung Chang, Arun Kumar Kuchibhotla, Alessandro Rinaldo
We consider the problem of inference for projection parameters in linear regression with increasing dimensions. This problem has been studied under a variety of assumptions in the…
A Sequential Test for Log-Concavity
Aditya Gangrade, Alessandro Rinaldo, Aaditya Ramdas
On observing a sequence of i.i.d.\ data with distribution on , we ask the question of how one can test the null hypothesis that has a log-concave density. Thi…
Mitigating multiple descents: A model-agnostic framework for risk monotonization
Pratik Patil, Arun Kumar Kuchibhotla, Yuting Wei +1
Recent empirical and theoretical analyses of several commonly used prediction procedures reveal a peculiar risk behavior in high dimensions, referred to as double/multiple descent,…
Denoising and change point localisation in piecewise-constant high-dimensional regression coefficients
Fan Wang, Oscar Hernan Madrid Padilla, Yi Yu +1
We study the theoretical properties of the fused lasso procedure originally proposed by \cite{tibshirani2005sparsity} in the context of a linear regression model in which the regre…
Generalized Results for the Existence and Consistency of the MLE in the Bradley-Terry-Luce Model
Heejong Bong, Alessandro Rinaldo
Ranking problems based on pairwise comparisons, such as those arising in online gaming, often involve a large pool of items to order. In these situations, the gap in performance be…
Optimal partition recovery in general graphs
Yi Yu, Oscar Hernan Madrid Padilla, Alessandro Rinaldo
We consider a graph-structured change point problem in which we observe a random vector with piecewise constant but unknown mean and whose independent, sub-Gaussian coordinates cor…
