Graph-Based Change-Point Detection
Hao Chen, Nancy Zhang
We consider the testing and estimation of change-points -- locations where the distribution abruptly changes -- in a data sequence. A new approach, based on scan statistics utilizi…

Graph-Based Tests for Two-Sample Comparisons of Categorical Data
Hao Chen, Nancy R. Zhang
We study the problem of two-sample comparison with categorical data when the contingency table is sparsely populated. In modern applications, the number of categories is often comp…

Change-point model on nonhomogeneous Poisson processes with application in copy number profiling by next-generation DNA sequencing
Jeremy J. Shen, Nancy R. Zhang
We propose a flexible change-point model for inhomogeneous Poisson Processes, which arise naturally from next-generation DNA sequencing, and derive score and generalized likelihood…
