Variance expressions for software reliability growth models
Swapna S. Gokhale · 2005
This paper derives a generic function to express the variance in the application reliability estimate in terms of the variances in the parameter estimates for the finite failure non homogeneous Poisson process (NHPP) class of software reliability growth models SRGMs. Based on the generic expression, we then derive an expression to obtain the variance in the application reliability estimate for one of the most influential SRGMs, namely, the Goel-Okumoto model. We illustrate the potential of the variance expression derived for the Goel-Okumoto model with several examples.
