Bootstrapping Interval Estimation for Software Reliability Assessment Based on an S-shaped Discretized Model

We discuss a simulation-based interval estimation approach for software reliability assessment. It is known that an S-shaped software reliability growth curve is often observed in an actual software testing-phase. Therefore, we focus on an inflection S-shaped model, which enables us to describe both of exponential and S-shaped software reliability growth curves flexibly, and discuss a bootstrapping method for software reliability assessment based on the inflection Sshaped software reliability growth model. In the interval estimation of software reliability, we apply three-types of bootstrap confidence interval estimation methods. Finally, we show numerical examples for our interval estimation approach based on the bootstrapping method by using actual fault-counting data.
