【摘要】 软件项目工作量估算在软件开发过程中一直扮演着重要角色。为了准确地估算软件项目工作量,提出了基于多元线性回归分析的估算模型。定义了软件项目中工作量估算的相关性和显著性因子。根据组织软件项目的历史数据,进行了相关性和显著性分析,确定影响软件项目开发的因子域;并利用最小二乘法对相关因子的系数进行回归。经回归后得到工作量与各因子的多元线性方程。通过多元线性回归模型的实际应用,表明该模型误差小精度高,为软件企业提供了一种简易而准确的工作量的估算方法。更多还原

【Abstract】 Workload estimation has played an important role in software project. A model base on multiple linear regression analysis are proposed to accurate estimate workload of soft project. Correlation factor and significance factor were defined. After analyze the nexus of factor and affect factor domain by the historical data,the multiple linearity regression equation is obtained,according to which the effort could be got. The application of the estimation mode proves that they could be offer an easy and accurate estimate way for most software organizations.更多还原
