The geometry average arithmetic average inequality is very important in mathematical analysis 摘要幾何平均算術(shù)平均不等式是非常重要的不等式。
According to the distributing regulations of prices of samples , we select arithmetic average data on the basis of the land proportion 根據(jù)樣點地價的分布規(guī)律,選用加權(quán)算術(shù)平均值作為某類某級土地的基準(zhǔn)地價。
New dominant forecasting method and redundant measure are defined for combination forecasting method with generalized weight arithmetic average , based on error of power of p 摘要從p次冪誤差的概念出發(fā),提出了廣義加權(quán)算術(shù)平均組合預(yù)測法新的預(yù)測方法優(yōu)超和冗余度的定義。
This paper provides the elementary proof of geometry average arithmetic average inequality , which can advance the use of the inequality significantly and can express its value through some applications 給出幾何平均算術(shù)平均不等式的初等證明,這樣就可使此不等式的使用大為提前,通過一些實例體現(xiàn)此不等式的使用價值。
Based on the characteristic of the industry measurement and control system , a kind of architecture for data fusion in industry measurement and control system is introduced , and some data fusion methods that can be used in industry measurement and control system were also introduced , such as arithmetic average , weighted average , recurrence estimate based on arithmetic mean , kalman filter etc 摘要根據(jù)工業(yè)測控系統(tǒng)的特點,給出了控制系統(tǒng)數(shù)據(jù)融合的一種結(jié)構(gòu),介紹了適合工業(yè)測控系統(tǒng)的幾種數(shù)據(jù)融合方法,如中位值法、加權(quán)平均法、算術(shù)平均與遞推估計法、卡爾曼濾波及多模型法等。
Evading risk in financial trading market cries for pricing options to a nicety . asian option , as the most flourish options in the finace market , the pricing has been focused on always . the exact pricing formula for the geometric average asian option had existed , but as to the european - style arithmetic average asian option , due to the dependence structure between the prices of the underlying asset , no analytical formula exists . on the hypothesis that the market is frictionless and without transaction costs 、 on the base of b - s ’ s and in the binomial tree model , we provide several algorithms for computing an accurate value of the european - style arithmetic average asian option . following rogers and shi and by jensen ’ s inequality , many different upper and lower bounds are provided ; meanwhile a formula have got by the comonotonicity and approximating the distribution function . all of the algorithms are easy for programming . with the development of computer , more accurater price can be computed quickly . and numerical example proved that these algorithms are very accurate 對于幾何平均亞式期權(quán)它的定價相對簡單,已經(jīng)給出了定價公式。對于算術(shù)平均亞式期權(quán),它的未定權(quán)益具有軌道依賴特性,一直沒有得到它的定價方程的解析解形式。本文基于對市場是無摩擦且在沒有交易費用的情況下,在b - s模型下,利用二叉樹模型給出了算術(shù)平均亞式期權(quán)定價方法;并總結(jié)了利用jensen ’ s不等式給出的各種不同情況下的上下界;同時應(yīng)用共單調(diào)性和近似分布函數(shù)的方法也給出了算術(shù)平均亞式期權(quán)價格的近似公式。
Calculated with nei ' s formula and the unweighted pair - group method with arithmetic averages ( upgma ) , the cluster analysis results demonstrated that the classification of seven strains of spirulina platensis with rapd markers is consistent with some of their physiological and biochemical characters as well as some molecular biological characteristics 用nei ’ s公式與歐氏距離類平均法對此擴增結(jié)果進行聚類與親緣關(guān)系分析。結(jié)果表明, rapd分類結(jié)果與7株材料的某些生理生化和分子生物學(xué)特性相吻合。
Firstly , the weighted value of every idiographic indicator in this system was established by analytical hierarchy process , and weighted arithmetic average was used to determine the analysis results of the indicators " values of six aspects . then the principal component analysis were used to calculate the principal component values of twenty enterprises that can be divided into five developmental types according to their principal component values . the five types were as follows : 1 ) highly developmental level and highly potential type ; 2 ) highly developmental level and lower potential type ; 3 ) highly developmental level and no potential type ; 4 ) low developmental level and highly potential type ; 5 ) low developmental level and no potential type 首先,通過層次分析法確定指標(biāo)體系中16項具體指標(biāo)的權(quán)重,并采用加權(quán)算術(shù)平均法確定6項評價指標(biāo)的評價結(jié)果;然后,結(jié)合gwbasic和spss軟件對六個方面指標(biāo)進行主成分分析,得出各企業(yè)的主成分得分;最后,通過聚類的方法將調(diào)查的20家涉農(nóng)企業(yè)分為五種不同的發(fā)展類型: 1 )高發(fā)展水平、高潛力型企業(yè); 2 )高發(fā)展水平、低潛力型企業(yè); 3 )高發(fā)展水平、無潛力型企業(yè): 4 )低發(fā)展水平、高潛力型企業(yè);和5 )低發(fā)展水平、無潛力型企業(yè)。
