差異量數
  1. The standard error of estimate, on the other hand, measures the variability, or scatter, of the observed values around the regression line.

    而估計值的平均誤差，卻是度量觀察值圍繞著回歸直線的變化程度或分散程度。
  2. Members further considered that the various measures introduced since last september such as the discount window, the convertibility undertaking in respect of the aggregate balance, and the movement of the convertibility rate for the aggregate balance by 1 pip per calendar day from 1 april 1999 had already stabilised the monetary system. to reduce further the scope for variability in the overnight interest rate could have the effect of making the system too rigid

    此外，委員認為去年9月以來推行的各項措施包括貼現窗總結餘兌換保證，以及1999年4月1日起總結餘兌換保證匯率每個公歷日調整1點子的措施已有效地穩定貨幣體系，若是進一步減少隔夜拆息變動的空間，可能會使制度變得過份僵化。
  3. The predictive value of heart rate variability is independent of other noninvasive measures commonly used to predict prognosis of cardiac diseases, low left ventricular ejection fraction, and so on. like other risk predictors, measures of heart rate variability have modest positive predictive accuracy when used alone. however, combining measures of heart rate variability with other risk predictors yields a positive predictive accuracy of about 50 %

    心率變異性的預測價值獨立於其他非創傷性預測心臟疾病預后指標（降低的左心室射血分數，頻發重復性室性心律失常等） ，在單獨應用時陽性預報率較低，但與其他指標聯合應用，陽性預報率可達50 。
  4. Besides, we show the method and result in the research of the heart rate variability. it is proved that the nonlinear analysis is much more effective in the clinical diagnoses of heart disease. by the end of this dissertation, we list some problems for our future works including chaos in discrete time ~ varying systems, srb measures of the chaotic map in the sense of marotto, complex dynamics of both h. h. model and cou - pled integrate - and - fire models, strange attractors in h6non systems with classical parameters

    在本文的第五章中，我們給出了一類一維時滯泛函微分方程穩定性的判別法，而這一方程本身可以用來刻畫連續的具有動態閾值的神經元模型；此外，我們介紹了非線性指標在心律變異中的具體應用與部分的分析結果，以進一步說明非線性分析在心律變異研究中的有效性和實用性
  5. We can calculate our measures of variability equally well for individual securities and portfolios of securities

    我們能夠同樣好的對個別證券和證券組合計算變異性的衡量標準。
