In this paper, we consider a latent Markov process governing the intensity rate of a Poisson process model for software failures. The latent process enables us to infer performance of the debugging operations over time and allows us to deal with the imperfect debugging scenario. We develop the...

We survey the literature on the accuracy of econometric software. We also assess the advantages of open source software from the point of view of reliability and discuss its potential in applied economics, which has now become fully dependent on computers. As a case study, we apply various...

Purpose – The purpose of this paper is to introduce a novel approach of designing, specifying, and describing the behavior of software systems in a way that helps to predict their reliability from the reliability of the components and their interactions. Design/methodology/approach – Design...
