  4. Since 1952 the markowitz ’ s mean - variance portfolio theory inception, sur - rounding this issue which how to measure risks, it has generated a lot of risk mea - surement methods and bring a lot of portfolio models, such as mean - semivariancemethods, mean - downside risk methods, mean - absolute deviation methods, mean - absolute semideviation methods, mean - absolute downside risk, and soon. 1999, duarte proposed a portfolio optimization uniform model that unifiedthe six methodologies mentioned above

    自從1952年markowitz的均值-方差投資組合理論問世以來，圍繞著如何對風險進行度量這一問題先後產生了許多的風險度量方法，帶來了很多的投資組合模型，如均值-半方差法、均值-下滑風險方法、均值-絕對離差方法、均值-絕對半離差方法、均值-絕對下滑風險方法等等。
  5. In second chapter, we obtain the second stage estimators for 0 and g with the first stage estimators by using generated least square th at is used in ev model. the second stage estimators are better than the first stage ones concerning variance, and meantime the paper proves that is the consistencey and the approximate normal distribution and gn is the consistency and the uniform consistency

    第二章首先在第一階段估計的基礎上，針對ev模型利用廣義最小二乘法求出， g的第二階段估計，這樣從誤差方差的角度來考慮，第二階段估計結果比第一階段估計結果改進了一步。
