摘　　要：研究考虑缺陷移除失败的软件缺陷预测改进模型,以提高缺陷预测能力.分析了传统Rayleigh模型的不足,在考虑缺陷移除失败因素的基础上,建立缺陷预测改进模型,并使用经验值及最大似然法估计获得模型参数.实例验证表明,改进模型可以有效地提高软件缺陷预测值与实际值的拟合度.To enhance the defect prediction ability, an improved Rayleigh model considering the factor of incorrect repair is presented. The shortcoming of the traditional Rayleigh defect prediction model was analyzed. The improved Rayleigh defect prediction model was established based on the consideration of the incorrect repair factor. The parameters of the improved model were obtained by using experience values and maximum likelihood estimation. Experimental verification shows that the improved model can effectively enhance the similarity between the prediction values and actual ones.
