数据的分类和权系数的确定

Classification of Data and Determination of Weight Coefficient

对于多指标数据的分类，通常将其投影到平面上，然后根据投影点的聚焦程度确定多指标数据的类别，分类的效果取决于权数的选取。利用广义最小二乘模型对多指标数据的权数进行了计算，进而实现对多指标数据的分类。

The multiple parameter data is usually projected on a plane and then the classification of it is to be decided according to the extent of the focus of the projection.The effects of the classification depends on the choice of weight coefficient.This essay deals with computing the weight coefficient of multiple parameter data with generalized least square model,thus realizing the classification of multiple parameter data.
