Hyper-geometric distribution software reliability growth model with imperfect debugging

Abstract

Debugging actions durin.g the test/debug phase of software d e ve1op.m e nt are la ot always performed perfectly. That is, not all th.e software faults detected are perfectly removed without introducing new faults. This phenomenon is called the imperfect debugging. The Hyper-Geo ni et ric Dist 1-i but i on software relia bilat y growth Model (HGDM) was developed for estimating the number of software fatilts initially in a program. In this paper, we propose a'n extended model based on the HGDM incorporating the notion of imperfect debugging.
