Software maintainability prediction

The pre-processing techniques were applied in the bug prediction datasets published in http://bug.inf.usi.ch/download.php by D'Ambros et al to produce a new version of these datasets that are suitable for software maintainability prediction. The independent variables are CK and OO metrics and the dependent variables is CHANGE metric.本研究对D'Ambros等人发布于http://bug.inf.usi.ch/download.php的缺陷预测数据集（bug prediction datasets）应用预处理技术，以生成适用于软件可维护性预测的新版本数据集。该数据集的自变量为CK度量与面向对象（Object-Oriented）度量，因变量为CHANGE度量。
