We model DNA count data as a multiple change point problem, in which the data are divided in to different segments by an unknown number of change points. Each segment is supposed to be generated by unique distribution characteristics inherent to the underlying process. In this paper, we propose a modified version of the Cross-Entropy (CE) method, which utilizes Beta distribution to simulate locations of change points. Several stopping criterions are also discussed. The proposed CE method… CONTINUE READING
