Module size distribution and defect density
Proceedings 11th International Symposium on Software Reliability Engineering. ISSRE 2000
Preserved Fulltext
We examine the available data sets and propose a model relating module size and defect density. ...
Does the overall defect density of a software project vary with its module size distribution? ...
Since we know both the module size distribution and the dependence of defect density on module size, we can calculate the total number of defects N given by the following equation. ...
