摘要   傳統迴歸分析是假設觀測值的不確定性來自於隨機現象,本文則應用模糊隨機變數概念於迴歸模式的架構,考慮將隨機現象和模糊認知並列研究。針對樣本模糊數(x<sub>i</sub>, Y<sub>i</sub>),我們進行模糊迴歸參數估計,並稱此為模糊迴歸模式分析。模糊迴歸參數估計大都採用線性規劃,求出適當區間,將觀測模糊數Y<sub>i</sub>的分佈範圍全部覆蓋。但是此結果並不能充分反映觀測樣本Y<sub>i</sub>的特性。本研究提出一套模糊迴歸參數的估計方法,其結果對觀測樣本的解釋將更為合理,且具有模糊不偏的特性。在分析過程中,我們亦提出一些模糊統計量如模糊期望值、模糊變異數、模糊中位數的定義,以增加對這些參數的模糊理解。最後在本文中也針對台灣景氣指標與經濟成長率作實務分析,說明模糊迴歸模式的適用性。
  Conventional study on the regression analysis is based on the conception that the uncertainty of observed data comes from the random property. However, in this paper we consider both of the random property and the fuzzy perception to construct the regression model by using of fuzzy random variables. For the fuzzy sample (x<sub>i</sub>,Y<sub>i</sub>), we will process the parameters estimation of the fuzzy regression, and we call this process as fuzzy regression analysis. The parameters estimation for a fuzzy regression model is generally derived by the linear programming scheme. But it`s result usually doesn`t sufficiently reflect the characteristics of the observed samples. Hence in this paper we propose an alternative technique for parameters estimation in constructing the fuzzy regression model. The result will describe the observed data better than the conventional method did, moreover it will have the fuzzy unbiased properties. For the purpose of fuzzy perception on the fuzzy random variables, we also give definitions for certain important fuzzy statistics such as fuzzy expected value, fuzzy variance and fuzzy median. Finally, we give an example about the Taiwan Business Cycle and the Taiwan Economic Growth Rate for illustration.
