摘要：
软件估算是软件开发中的重要活动，而类比估算是软件估算中最常用、最易于理解的方法。为了表征软件项目属性对软件估算结果的不同影响程度，类比估算通常采用加权算法。我们采用多元线性回归方法估计类比估算的加权参数，提高了估算活动的工作效率，同时也可以提高估算结果的准确性。
关键词: 线性回归 类比方法 软件估算
Abstract:
Software estimation is a significant activity in software development. Analogy is the most common and comprehensible method among software estimation methods. In order to describe the difference influence of software project attribution to estimation resulting attribution, an analogy method is introdu ced. We use the multiple linear regression method to predict the weighted coefficient, which increases the efficiency of estimation, and improves the pr ecision of result.
Key words: linear regression, analogy method, software estimation
