信息集成方法选择变量与判别分析的应用

Choosing Main Variables by Use of the Method of Information Integration and the Application of the Discrimination Analysis

针对自变量较多,但每一变量携带信息较少的情况,提出通过信息集成选择主要变量的方法。经过相关分析检验,再应用马氏距离判别进行地震预报。模型由主成分分析、相关分析、马氏距离判别组成,利用华北地区地震数据进行了地震预报,取得了较好的效果。

This paper deals with the problem how to choose the main variables from many variablesusing the method of information integration. After tested, then use the Mahalanobis discriminationanalysis to predict earthquake. The model consists of principal component analysis and correlationanalysis and discriminate analysis. We applied this model to analysis the earthquake in the Huabeidistrict and obtained satisfied result.
