We discuss a bootstrap method for software reliability assessment based on a discretized no homogeneous Poisson process (NHPP) model. Ordinarily, model parameters of the discretized NHPP model are estimated by using the regression analysis based on the regression equation derived from a difference equation of the discretized NHPP model. However, it is not so easy to derive some information for the...
We often observe a phenomenon that stochastic characteristics of the software failure-occurrence time or software failure-occurrence time-interval changes notably in an actual testing-phase of a software development process. The testing-time when such phenomenon is observed is called change-point. It is said that the effect of change-point on the software reliability growth process influences accuracy...
This paper discusses two-dimensional software reliability measurement technologies, which describe a software reliability growth process depending on two-types of software reliability growth factors: Testing-time and testing-effort factors. From the view point of actual software failure-occurrence mechanism, it is natural to consider that a software reliability growth process depends on not only testing-time...
Testing-time when a characteristic of a software failure-occurrence or fault-detection phenomenon is notably changed is ordinarily called change-point. The effect of the change-point on software reliability growth process influences on accuracy of the software reliability assessment based on SRGMs which are mostly developed under the assumption that the stochastic characteristic of the software failure-occurrence...
