查询词典 factor model

What's more the relations between different asset are classified to three groups which are the fundamental-derivative relation、the cross sectional relation and the comprehensive relation, on basis of which the asset pricing anomalies are classified individually to different groups.(2)The price model of the capital asset is constructed trailing the path of the asset value's incrementing and transferring. And then a three–factor model is established which can be utilized by the empirical researches. Concretely, under the capital chain, we conclude the relation between the stocks and the corporate assets is a fundamental-derivative one and the research object is the capital asset under the capital chain.

具体而言，本文在资产链的角度下分析股票和公司资产之间的"基础—衍生"关系，明确了本文的研究对象为资产链下的资本资产；建立了公司资产的价值，将公司资产和其基础资产公司的财产联系了起来，构造了资产链上第一个节点——公司资产的价值；将公司资产和资本资产进行了关联，在考虑公司资产变为资本资产的流动性增值后，建立了资本资产的价格模型；在前文资本资产价格模型的基础上进行了收益分解，基于此引入了具有长中短不同决策周期的三类投资者，在存在无风险资产和不存在无风险资产两种情况下分别建立了可用于实证的三因素模型。

The first section is introduction; the second and the third sections discuss the parametric estimation; the fourth section is about the choice of factors, model test and characteristic model; the application of factor model in risk management will be discussed in the last section.

具体内容安排如下：第一章首先介绍本文研究的理论与现实意义；然后基于SDF定价框架，详细地论述了本文所要研究四个问题的内在联系，同时也为本文后面的模型讨论提供了一个框架；最后给出本文的研究主要内容和主要创新之处。

We use the approximate distribution comes from probability generating function of CreditRisk+ to value the CDO under the single sector factor and multi-sector factors scenarios. For single sector factor model, we discuss the sensitive analysis of CDO fair spread by different default probability, default correlation and loss given default. For multi-sector factors model, we exam the CDO fair spread based on different sector correlation assumption, such as Gamma distribution in moment match method, multivariate Gamma distribution and compound Gamma distribution.

本文在信用风险加成模型之下，利用机率产生函数的近似分配评价抵押债务债券，并考虑单一部门因子与多个部门因子，单一部门因子中，在不同违约机率、违约相关系数和违约损失率下，探讨抵押债务债券公平价差之敏感度分析；多个部门因子中，在不同相关性部门因子分配假设下，如动差配适法的伽玛分配、多维伽玛分配、复合伽玛分配，探讨抵押债务债券公平价差之方法结果比较。

PCA is to perform the variable transformation, whereas factor analysis needs to form a factor model.

主元分析只是进行一定的变量变换，而因子分析则需构成因子模型。

Exploratory factor analysis, confirmative factor analysis, and analysis of variance were used to analyze the datum, which was based on the investigation we carried out for three times in Bank A, and there were more than 700 people involved. Whats more, we tested the reliability and validity of the scale thoroughly, and we established a four-factor-model for Bank A in the background of Chinese culture.

基于前后三次在A银行共计700余人次的问卷调查，对采集的数据进行了探索性因素分析、验证性因素分析、方差分析等，并对研究结果的可靠性和有效性进行了全面的检验，建立了A银行员工岗位角色适应的四因素模型。

The CVD is an important index to indicate tree diameterdifferentiating.On basis of dynamic change and tendency of CVDamong trees in stand,three models of square CVD are proposed.i.e.,basic model,stand factor model,and thinning effects model.All threemodels are of mechanism,asymptotic characteristic,and invariance forprojection length.Futhermore,there are compatiability and extremevalues in thinning effects model for thinned and unthinned stands.

直径变动系数是描述林木直径分化的重要指标，根据林木直径变动系数的动态变化和趋势，本文提出了直径变动系数平方动态变化的三个模型：基本模型，与林分因子相关的模型，考虑间伐效应的模型，上述三个模型均具有一定的机理性、渐近性和步长不变性，特别是考虑间伐效应的模型为间伐林分和未间伐林分的相容性模型，它还具有相容性和极值性。

The assuption that independence between different sector risk factors is an obvious drawback of the original CreditRisk+ model. The amened model such as the single factor model, the compound gamma CreditRisk+ model and the two stage CreditRisk+ model still have their own problems.

行业风险因子之间相互独立的假设是原CreditRisk+模型的明显缺陷，随后对其进行修正的单因子模型、复合Gamma CreditRisk+模型和两阶段CreditRisk+模型仍存在问题。

Finally, the empirical result of the single systemic factor model showed that the common factor Z had periodicity existed; that is to say, if Z was negative in average within the first quarter, then that meant the overall economic situation in that quarter was not good, and affected every enterprises credit ratings declining.

最后，单一因子模型的实证发现，共同因子存在一个周期性，即每年的第一季Z均为负，表示该季总体经济状况不好，使得平均每一家企业的信用评等均下降，每年的二四季Z均为正，表示这三季的总体经济状况良好，使得平均每一家企业的信用评等提升。

Introducing volatility index in French etal(1987) and based on the above four-factor model, we bring forward a new perspective to discuss idiosyncratic risk, and we also bring forward a new model of intra-day liquidity to investigate the corresponding risk premium.
