A Comparison of Two-Stage Scheme and Fully Sequential Sampling Scheme for Estimating Software Reliability
2020
International Journal of Emerging Technology and Advanced Engineering
Preserved Fulltext
Our goal of this scheme is to obtain the near-optimal choices for distributing of test cases among sub-domains by minimizing the variance of the overall software reliability estimator. ...
Also, the two-stage sampling scheme is expected to perform better than a balanced sampling scheme by virtue of lower the variance incurred by the overall estimated software reliability ...
We are using a classical approach by aiming to minimize the variance of overall estimated software reliability incurred by the maximum likelihood estimator. ...
