Test for parameter change in diffusion processes by cusum statistics based on one-step estimators



Yoichi Nishiyama (The Institute of Statistical Mathematics, Tokyo), 3 November 2004

We consider the problem of testing for a parameter change using the cusum test based on one-step estimators in diffusion processes. It is shown that under regularity conditions the cusum test statistic has the limiting distribution of a functional of Brownian bridge.
