In this paper we examine the reporting pattern of more than 7000 issue reports from five large open source software projects to evaluate two main characteristics: (1) when do defects get reported - does there exist any distinct patterns, and (2) is there any difference between reported defect in ow and actual defect in ow for these projects. The two questions evaluated here are important from practical standpoint. Detailed knowledge of specific patterns in defect reporting can be useful for planning purposes, while differences between reported and actual defect in ow can have implications on accuracy of dynamic software reliability growth models used for defect prediction/reliability assessment. Our results suggest that while there exist distinct variation over when defects are reported, the ratio of reported to actual defects remains fairly stable over period of time. These results provide more insights into possible group of people who contribute to OSS projects and also enhance our confidence in applying SRGMs using reported defect in ow. Our test with logistic growth model show that using reported bugs provided asymptote (total expected bugs) predictions that were on average only 4.8% different than using actual bugs for making such predictions. Keywords Software defects, Issue reporting, Mining software repositories, Bug reports, Data quality, Open source software, SRGMs.
