  1. A portfolio selection model on copula - garch - evt based and its hybrid genetic algorithm

    的資產組合選擇模型及其混合遺傳演算法
  2. The results show that evt performs better than lognormal pdf for real data sets characterized by high indoor radon concentrations

    結果顯示極端值理論對高氡氣濃度分佈區域之預測佳於一般對數常態分佈模式。 。
  3. One is the evt - based var model ( including gev model and gpd model ), the other is the quantile regression var model. secondly, i evaluate predictive performance of a selection of var models for chinese stock market data. these var models include riskmetrics method, historical simulation, monte carlo method, and the three recent models based on quantile regression and extreme value theory

    本文首先重點探討了極值分佈var模型（包括廣義極值分佈和廣義帕雷托分佈兩個模型）和分位數回歸var模型；然後在此基礎上將六個var模型（包括上述三種模型、歷史模擬法、 riskmetrics方法以及蒙特卡洛法）實證應用於估計上證指數、上證180 、深證成指、深證綜指95 var和99 var ；同時採用區間預測法、損失函數法和符號檢驗法對這些var模型進行了選擇評估。
  4. Traditional var methods want to give a hypothesis of financial return data subjected to some distribution, which brings about the suspicion of validity of hypothesis. however evt educes the tail of distribution instead of the hypothesis

    傳統上， var計算方法一般都要對金融收益服從哪一類型分佈進行假設，這就不可避免地對這一假設的有效性產生懷疑。
  5. Because evt mainly studies extreme value and models the tail of distribution financial return, it can effectively forecasts and guards against the financial risk on the condition of lacking of sample data. more and more people recognize the great potentials of evt dealing with the risk of extreme event. especially evt can be used in application to value at risk due to modeling the tail of distribution

    極值理論主要以極值為研究對象，它注重模擬收益分佈的尾部，比較有效地解決了在缺少樣本的客觀條件下如何預測和防範金融風險的問題，因此，越來越多的人認識到極值理論在極端事件風險管理中的巨大潛力，特別指出的是極值理論是一種模擬收益分佈尾部的理論，所以可以應用於風險價值的測量。
  6. It is now mostly used in hybrid electrical vehicles ( hev ) as an energy transducer and the electrical variable transmission ( evt )

    它主要作為能量變換器以及電無級變速器應用在混合動力車上。
  7. Chapter three introduces the basic knowledge of evt and the var method using evt

    在第三章中主要介紹了極值理論的基礎和計算步驟。
  8. So it can avoid risk of model and computer rightly the var of extreme event. this article presents the theory of extreme value and character of tail of distribution and gives the example of var with index of shanghai stock market by evt, then compares the var result of different computation methods and concludes that traditional var method is static state model and var with evt is dynamic conservative model and has the ability of forecasting risk out of sample comparing to historical simulation method

    本文系統地闡述了極值理論和極值分佈特徵，以上證指數為例，將極值理論應用於風險價值的計算，並將應用結果與傳統var方法計算的結果進行了比較分析，最後得出結論：傳統的var計算模型是靜態的模型，應用極值理論計算var的模型是動態的、相對保守的模型；與歷史模擬法相比較，極值理論具有超越樣本的預測能力。
  9. In this paper, global and local indoor radon distributions are modeled using extreme value theory ( evt )

    本文中全球及地區室內氡氣濃度分佈使用極端值理論。
  10. The extreme values which lies in the tail are some rarely happened events that have significant influence. extreme value theory ( evt ) is the statistical model to study the behavior of extreme v alues

    分佈在尾部的點都是一些極少發生但又具有顯著影響的觀測值，或者稱為極值，極值理論是對這些極值提供統計分析的模型。
  11. The theory of extreme value ( evt ) is a branch of order statistics, which traditionally can be used as a tool forecasting tsunami, earthquake and flood. recently it has been applied to financial risk management

    極值理論是次序統計學的一門分支，傳統上被用來預測海嘯、地震、洪水等自然災害，近年來已被廣泛地應用於金融風險的管理中。
  12. Level 6 - evt services counter

    第六層-電動車服務櫃臺
  13. Property with the ". evt " file name extension

    屬性的前八位字元後面進行設置的。
