Abstract

Consider a statistical sample of independent measurements, where at some unknown point a change in the mean has occurred. We are interested in detecting the point of change in the distribution. We introduce two estimators of the time of change and compute their asymptotic limit distributions as the sample size goes to infinity. The results are derived for each of the following three possibilities: finite change in the middle of the sample, small change in the middle and early finite change.
