In this paper we extend an earlier worst case boundreliability theory to derive a worst case reliabilityfunction R(t), which gives the worst case probability ofsurviving a further time t given an estimate of residualdefects in the software N and a prior test time T.The earlier theory and its extension are presented andthe paper also considers the case where there is a lowprobability of any defect existing in the program. For the"fractional defect" case, there can be a high probabilityof surviving any subsequent time t. The implications ofthe theory are discussed and compared with alternativereliability models.Keywords: reliability prediction, reliability testing, worstcase reliability bound, residual fault prediction.
