Successfully predicting defect-prone software modules can help developers improve product quality by focusing quality assurance activities on those modules. Emerging repositories of publicly available software engineering data sets support research in this area by providing static measures and defect data that developers can use to build prediction models and test their effectiveness. Stratifying NASA data sets from the PROMISE repository according to module size showed improved prediction performance in the subsets that included larger modules.
