“C—D”因子分析及其在矿产资源定量预测中的应用

在数学地质诸方法中,多元统计分析,地质统计学等是用来处理定鼍变量的,而数量化理论,马尔柯夫链,逻辑信息法等仅适于定性变量。本文介绍一种新的方法——“C—D”因子分析方法,它既适于定量变量,也可用于定性变量,当定性变量和定量变量同时存在时也同样适用,将它用于矿产资源定量预测,应用效果良好。

C-D" FACTOR ANALYSIS AND ITS APPLICATION IN QUANTITATIVE PREDICTION OF MINERAL RESOURCES

The method of C-D factor analysis, applied not only in the reserach of quantitative variatc but in that of qualitative variatc ,can be applied in the sitution when quantitative and qualitative variatcs coexisted at the same time. The train of this method is calculating the correlation coefficients of different variatc firstly, then calculating the integrating matrix after a scries of matrix transformation .and then getting the eigenvalue and eigenvector of this matrix,finally obtaining the factor loading and score of sample unit, which is the quantitative basis for the interpretation of natural geological problems. It is shown that this method is good applied in quantitative mineral resources prediction.
