摘　　要：不完整数据是实际中经常遇到的问题.在对这种数据进行分类或统计时,由于缺乏一些数据,结果则往往不尽人意.对缺失数据给定一个初值,通过实验发现,在给定初值的情况下,会得到比较满意的结果.Incomplete data is what we often encounter in practical problems. In classification or statistics of this sort of data,due to the lack of some data,the results are often unsatisfactory. In this paper,an initial value given to some missing data,it＇s found through the experiment that the results are relatively satisfactory in the case where initial value is given.
