| Abstract(in English) | This paper focuses on bug reports in open source developments, and discusses about abilities for modeling and predicting amount of bug reports, using growth curve models. The empirical study performs a data collection of 2,997 bug reports from three versions of Apache Tomcat (Tomcat 3, 4 and 5), and shows that Weibull curve model, a flexible growth curve model, could be used for modeling changes in cumulative bug reports. Moreover the paper focuses on differences in severities of bugs and differences in the software versions as well. Through the data analyzes, the results give the following findings: (1) differences in severities have no impact on the forms of growth curves; (2) differences in the software versions have some impacts on the growth curves-the initial version has an exponential curve but the later versions have S-shaped curves. |
