WebRayleigh Model, among the family of Weibull distribution, is found to be most. suitable for predicting reliability of software product. It predicts the expected. value of defect density at different stages of life cycle of the project, once. parameters (total number of defects or total cumulative defect rate and peak of. WebA software reliability growth model (SRGM) can be regarded to be a mathematical expression which fits the experimental data. It may be obtained simply by observing the overall trend of reliability growth. How- ever some of the models can be obtained analytically by making some assumptions about the software test- ing and debugging process.
