Nonparametric Cusum Charts for Angular Data with Applications in Health Science and Astrophysics

Methodology 2018-06-08 v2

Abstract

This paper develops non-parametric rotation invariant CUSUMs suited to the detection of changes in the mean direction as well as changes in the concentration parameter of angular data. The properties of the CUSUMs are illustrated by theoretical calculations, Monte Carlo simulation and application to sequentially observed angular data from health science and astrophysics.
