Stationary Distribution Convergence of the Offered Waiting Processes in Heavy Traffic under General Patience Time Scaling

no code implementations9 Feb 2021 Chihoon Lee, Amy R. Ward, Heng-Qing Ye

In this paper, we further show that the sequence of stationary distributions and moments of the offered waiting times, with diffusion scaling, converge to those of the limit diffusion process.

Direction-Projection-Permutation for High Dimensional Hypothesis Tests

1 code implementation2 Apr 2013 Susan Wei, Chihoon Lee, Lindsay Wichers, Gen Li, J. S. Marron

Motivated by the prevalence of high dimensional low sample size datasets in modern statistical applications, we propose a general nonparametric framework, Direction-Projection-Permutation (DiProPerm), for testing high dimensional hypotheses.
