查询词典 expectation value

This paper presents the portfolio selection problem of two-attribute money and creates a model of portfolio selection based on two-attribute money, which can both contain the existing portfolio models and overcome the above-mentioned deficiencies. A series of new concepts is put forward, such as, holding wealth, obtainable wealth, short-term utility function, short-term expectation-variance utility function, state-expectation-variance utility function, short-term expectation-variance utility curve, long-term expectation-variance utility curve, margin utility contribution force, additional contribution force, profit-risk exchange rate and optimal portfolio expansion curve; The state-expectation-variance analytical method is developed from the expectation-variance analytical method; A set of systematic theories concerning two-attribute portfolio selection is thus established.

本文提出了两属性货币的证券组合选择问题；创建了既能包含现有证券组合选择模型又能克服上述两点不足的两属性证券组合选择模型；提出了持有财富、可获财富，短期效用函数，短期期望—方差效用函数、状态—期望—方差效用函数，短期期望—方差效用曲线、长期期望—方差效用曲线，边际效用贡献力，附加贡献力，收益—风险替换率，最优证券组合扩展线等一系列新概念；把期望—方差分析方法发展成状态—期望—方差分析方法；建立了两属性证券组合选择模型的一套系统的理论。

Chapter six presents such new concepts as margin utility contribution force, profit-risk exchange rate, state-expectation-variance utility function, long-term expectation-variance utility curve and optimal portfolio expansion curve. The state-expectation-variance analytical method is developed from the expectation-variance analytical method. The changing rate of profit-risk exchange rate to state variable is used to define and distinguish the decreasing, constant and increasing relative risk aversion. A decomposition formula about the margin contribution force of holding wealth to state-expectation-variance utility function is displayed. The decomposition formula demonstrates that the contribution force of investors' holding wealth to their utility is composed of the pure contribution force of holding wealth and the investment contribution force bronght about through investment portfolio.

第六章提出了边际效用贡献力、收益—风险替换率、状态—期望—方差效用函数、长期期望—方差效用曲线、最优证券组合扩展线等新概念；把期望—方差分析方法发展成状态—期望—方差分析方法；用收益—风险替换率对状态变量ω的变化率来定义和区分递减、定常、递增相对风险厌恶；获得了持有财富对状态—期望—方差效用函数的边际贡献力的分解式，该分解公式表明投资者的持有财富对他的效用的贡献力由持有财富本身的纯贡献力和持有财富通过投资证券组合所产生的投资贡献力所组成。

Results: Normal university students got higher self-expectation scores of firmness, frankness, candidness and enterprise, lower scores of slovenliness, quietness and dressiness. Their gender partners were expected to be very allowable, firm, family-oriented, magnanimous and candid, not to be too slovenly, quiet and dressy. Male students were expected to be strong and enterprising, female being kind, quiet, dressy and lovingly. Students from cities got significantly（P＜0.05,P＜0.001＝higher self-expectation scores of kindness and dressiness than those from countryside. They expected their gender partner to be stronger, more cool-minded and enterprising significantly（P＜0.05,P＜0.01,P＜0.001＝than students from countryside.

According to the principles of total economic value, the first step of the evaluation of assets value of wetland is to classify the assets value into two categories: use value and nonuse value , the former include direct use value and indirect use values , and the later includes existence value and Bequest value , the option value belongs to non-use value because its use value can not be realized.

对湿地资源资产价值的核算，应根据总经济价值的原理，首先将其资产价值分为使用价值和非使用价值两大类；使用价值又进一步分为直接使用价值和间接使用价值；非使用价值则包括存在价值和遗产价值；选择价值由于目前无法实现其使用价值，因此属于非使用价值的范畴。

Value is the product of the relationship of demand and supply between subjects and objects Subjects consist of three levels such as human totality,groups subjecting to the human totality,and human individuals Coresponding to it,objects include the outside world with respect to human totality（groups+individuals+the world outside human being）,the outside world with respect to human groups,and the outside world with respect to human individuals Therefore,things possess value,so do human beings Because humans themselves are the unity of subjects and objects,humans have selfvalue The reciprocal function of the factors constituting value decides the production of value,promote the changes of value,which is the basic subject of thelaw of value The three factors which have influence on the changes in value are the demand of subjects.the character of objects.and practice The origin of the conflicts of value concepts lies in the differences and opposites of the living conditions of human subjects The direct originis the differences and opposites of value objects Therefore,in order to gradually eliminate the conflicts of human value concepts,the differences of the living conditions of human subjects must be eliminated thoroughly

价值是主客体之间需要与满足关系的产物。主体有人类整体、人类整体之下的群体以及人类个体三个层次，与之相应，客体也包括与人类整体相对的外部世界（群体+个体+人以外的世界）、与人类群体相对的外部世界以及与人类个体相对的外部世界。因而不仅物具有价值，人亦有价值。由于人自身是主客体的统一，因而人还有自我价值。构成价值的各个要素相互作用决定价值的生成、推动价值的变化，这是价值规律的基本内容。影响价值变化的主要有主体需要、客体属性及实践三个要素。价值观念冲突的最终根源在于人类主体生存条件之差别和对立，直接根源则在于价值客体的差别和对立。因而要逐步消除人类价值观念的冲突就必须从根本上消除人类主体生存条件方面的差别做起。

The dissertation recommends some kinds of methods and measures: such as adjusting the network configuration, connecting value and threshold value by the total value of all stylebooks, adding part of the adjusting value of the last time to the current adjusting value, transforming the stylebooks to standard value, optimizing activation function, appending threshold value to the putout of the nerve cell and so on. Simultaneity, the author brings forward a new method to optimize the model of artificial neural network . It is using the automatically adaptive genetic algorithm to make the network configuration, connecting value and threshold value of artificial neural network better. The method can make the model better and improve the simulating effect and forecasting precision.Genetic algorithm is an arithmetic based on evolution and genetics used to search the optimization .
