On development of change point based generalized SRGM for software with multiple releases

The concept of change point has been widely discussed with respect to fault removal process of single release software only. In this paper, we propose a discrete generalized modeling framework for multi-release software system by applying the concept of change point on some standard discrete probability distributions to model the fault removal process. Parameter estimation has been done and goodness-of-fit is analyzed on real life 4-release failure dataset.
