Here it is possible to download the bug prediction dataset for the 5 listed software systems. All the files provide data at the class level. For each system, it is possible to either download a zip file with everything or individual metrics.
Eclipse JDT Core
Download everything or choose from the list:
- Object oriented models of 91 bi-weekly versions of the system (each model/version is an mse file)
- Bi-weekly values of the CK metrics (91 versions of the system)
- Bi-weekly values of 11 object oriented metrics (91 versions of the system)
- Categorized (with severity and priority) past defects
- Change metrics (15) plus categorized (with severity and priority) post-release defects
- Churn of CK and other 11 object oriented metrics over 91 versions of the system + weighted, linear, exponential and logarithmic variants
- Entropy of CK and other 11 object oriented metrics over 91 versions of the system + weighted, linear, exponential and logarithmic variants
- Complexity of code change + weighted, linear, exponential and logarithmic variants
- CK and other 11 object oriented metrics for the last version of the system plus categorized (with severity and priority) post-release defects
