Global Testing Against Sparse Alternatives under Ising Models
Rajarshi Mukherjee, Sumit Mukherjee, Ming Yuan
In this paper, we study the effect of dependence on detecting sparse signals. In particular, we focus on global testing against sparse alternatives for the means of binary outcomes…
Detection Thresholds for the -Model on Sparse Graphs
Rajarshi Mukherjee, Sumit Mukherjee, Subhabrata Sen
In this paper we study sharp thresholds for detecting sparse signals in -models for potentially sparse random graphs. The results demonstrate interesting interplay between graph…
On Estimation in Tournaments and Graphs under Monotonicity Constraints
Sabyasachi Chatterjee, Sumit Mukherjee
We consider the problem of estimating the probability matrix governing a tournament or linkage in graphs from incomplete observations, under the assumption that the probability mat…
