When a bug is fixed, programmers are supposed to report where it is repaired. The association of the bug, and the repair is critical to quality-improvement efforts, such as bug prediction and defect etiology and avoidance. But what if programmers don't tell us where all the bugs are fixed?If they fail to report bug fixes, or worse, do the reporting in a slective manner, we might get a biased sample of bug-repair data, which would threaten the validity of studies using this data.
Dozens of papers have been written using open-source bug-repair data. We have studied this data for evidence of bias in reporting, and evaluated the potential effects of this bias on prediction.
