本文以機械業為例，完成經營變數五行生剋加權相關係數的邏輯探討。釐清特定個體分析、總體分析、及代表性個體分析三種情境下的相關係數涵義。釐清個體的個體性及其客觀相對重要性。完成五行生剋加權相關係數與加權迴歸分析的精確聯繫。對機率理論的極限定理的立論前提也有一些批評。

In this paper, using Machinery Manufacturing data as an example, the author accomplished the logical investigations of weighted correlation coefficients in Wu-Hsing Sheng-Ke (五行生剋) of business variables. The implications of correlation coefficients in three kinds of situations: specific micro-data analysis, macro-data analysis, and representative micro-data analysis, were clarified. Both individualities and their objective relative importances of micro-data were often ignored before, but they were clarified in this study. The fine connections between weighted correlation coefficients and weighted regression analysis were accomplished. Comments were also made on the inference premises of limit theorems in probability theory.
