  1. Based on rough sets theory, crude domain knowledge rules are extracted ; dependent factors and antecedent coverage factors of rules are calculated from sample data

    該方法充分利用軟計算中的模糊集合理論，人工神經網路，粗糙集理論和遺傳演算法等計算方法優勢，彌補它們相互的不足，進行故障診斷。
  2. However, via intensive numerical computation, the author finds that actually some characteristic of this confidence intervals, for example, confidence coefficient, expectation width and coverage efficiency fluctuate intensely when the sample size varies given the parameter, or when the parameter varies given the sample size

    但是我們通過精細的數值計算發現，由於總體分佈的離散性，這些置信區間的特性（置信系數、期望長度、覆蓋效率）實際表現為當參數固定隨著觀測次數（樣本值）變化或當觀測次數固定隨著參數變化而發生強烈震動。
  3. When the parameter is fixed, sometimes the coverage probability may decrease with the increase of sample size, which is abnormal phenomenon, that is to say, there exists so called " unluky point "

    當參數固定時，會出現樣本量增加反而會使覆蓋概率下降的反常現象，即存在所謂的「不幸點」問題。
