Non-Parameter Test for Change-Point of Scale Parameter

Abstract
The change-point problem about the scale parameter is discussed in this paper. Based on two-sample U-statistic two tests are proposed, and their approximate distributions, which are \sup\limits_0<t<1|B(t)| and extreme valve distribution respectively, where \B(t),0\le t\le 1\ is a Brownian bridge, are obtained.
