Previous research on closed-source software found that highly coupled software modules were more defect prone, which makes it important to understand the effect of coupling on defect proneness in open-source software (OSS) projects. For this purpose, we used Cox proportional hazards modeling with recurrent events. We found that the effect of coupling was significant, and we quantified this effect on defect proneness.
