基于三对象的三维标度法及其应用

A Multidimensional Scale Method Based on Triple Objects and its Application

本文介绍了基于三对象（样品或变量）的多维标度法。计算方案是通过一维标度求法（数量化理论Ⅳ的扩展）和多维标度法把原始问题降至为标准特征值－特征向量问题来解决。该方法的主要目的是提取更多信息、简化数据结构，并重新标度研究对象于新的低维空间，以便能通过二维“因子轴”来直接检验。它适合于定性和定量数据。编写计算程序进行标度分析，在内蒙古赤峰某金矿进行矿产了预测。

This paper presents a multidimensional scale method which based on triple objects (Samples or variables).The computational scheme is reducing an original problem to a standard eigenvalue——eigenvector by use of one dimensional scale method (development of quantification theory Ⅳ) and multidimensional scale method.The major goal of the method is to get more information and simplify data structure, and rescale researching objects into a new and reduced space ,so that patterns and relations of original object can be directly examined in two dimensional “factor” plots ,it is applied to quantitative and qualitative data.A compute program is compiled to perform Pijk analysis .The approach is carried out in gold mineral prediction in chifeng,Inner mongolia with pretty good results .
