摘　　要：软件缺陷是软件质量评价的重要依据,需要全面而深入的研究与分析,而同时导致软件缺陷形成的因素却多种多样,难以确定软件缺陷的生成原因。因此,为了分析软件缺陷的生成原因以及发现缺陷的方法,文中研究了基于多元线性回归的线性拟合方法,从被测对象、开发与测试人员、测试强度等方面研究对软件缺陷的影响。首先对软件缺陷的生成因素进行分析,并选定5个因素作为分析变量,建立分析模型。之后通过数据分析获得了回归方程,并依据方程确定各因素对软件缺陷生成的影响程度。通过分析获得的各因素的t检验值可知,测试时间对软件缺陷的生成影响最大,而软件复杂度和开发人员经验也对软件缺陷的生成具有较大的影响。Software defects is an important basis for software quality evaluation,so it is necessary to thoroughly and deeply research on it.However the reasons rising software defects are too complicated to identify. In this paper,for analyzing the reasons for the generation of software defects and the methods of finding defects,based on linear fitting method of multiple linear regression,study the effects of software defects from the tested object,developers and testers,testing strength and so on. First,5 factors were selected to build analysis model. Second,the regression equation was obtained by analyzing the data and the factors degree of influence on software defects generating were determined. Finally,by analyzing the t value,it is found that the strength of time is the most significant factors and the complexity of software and developers experience also have important influence in software defect generation.
