本文利用极值理论对中国商业银行操作损失极端值分布进行估计，针对尾参数估计的来用传统Hill佑计对小样本数据容易产生偏倚的情况，提出了采用Hill佑计的改进―小样本无偏估计的HKKP佑计来估计操作损失的尾参数，针对由于阈值确定不准确导致结果偏差大的情况，采用最小化估计的累计概率分布与经验累计概率分布平均平方误差的方法确定较精确的阈值，估计出给定置信水平下操作风险损失的分位数，从而使得中国商业银行操作风险监管资本的测定成为可能。

After that, the article expounds how the social labor value theory overcomes the theoretical hard nuts in the financial accountings:(1) it has solved the issue of conformity between the production domain and accounting domain by holding that the social labor creates the value, which decides that the domains of production and accounting should be extended to cover the tertiary industry;(2) it has solved the issue of the valuation standards in the economic accounting by holding that the theoretical value should be converted into the actual value and that only when the price of production is used as the valuation standards can the financial accounting and economic accounting have a true valuation basis;(3) it has solved the issue of creation and distribution of surplus value and explicitly points out that the power of science and technology determines that the surplus value comes mainly from the materialized labor. Only when we have a clear understanding of this point and have realized that the value of product is created jointly by the materialized labor and the laborer can we straighten out the relationship in the distribution of earning inside the enterprise and understand that the distribution on the basis of contributed capital is a reasonable choice at present.

其次，着重阐述了社会劳动价值论如何解决经济核算中的理论难题：一是解决了生产范围与核算范围的统一问题，认为社会劳动创造价值，决定了生产范围与核算范围都必须扩大到第三产业；二是解决了经济核算的计价标准问题，认为必须从理论价值转化为实际价值，用生产价格作为计价标准，才能使会计核算和经济核算真正具有计价基础；三是解决了剩余价值的创造与分配问题，并明确指出，科技的力量决定了剩余价值主要来自于物化劳动，只有认清这点，承认企业的产品价值是物、活劳动共同创造的，才能真正理顺企业的利益分配关系，才能理解按资分配是现实合理的选择。

In order to reduce calculation error, the frequency distribution of average values is used to compute the mixed distribution's digital features of each component distribution, thereinto, the number of the component distribution is determined by AIC, choose the number that meets the minimum value of AIC as the component number of mixed distribution, and the other parameters are estimated by EM algorithm; Secondly, because each component distribution is corresponding to a kind of major gene genotype, according to the values of the average and variance of the each component distribution, we can use the limit error of the normal distribution to plot each individual into the correspondent component distribution, namely into correspondent major gene genotype. Then we regard each major gene genotype as a treatment level of one-way analysis of variances, and the one-way multivariate analysis of variance is carried out to calculate the covariance matrix of major gene effect, covariance matrix of polygene effect, covariance matrix of environment effect and so on; At last, combining the weights of the each component distribution of mixed distribution, we can calculate the variance of major gene effect, the variance of polygene effect, environmental variance and the genetic gain of the quantitative trait.

为减小计算误差，本研究采用均值的频数分布来计算各成分分布的数字特征，其中成分分布个数根据AIC准则，选择使AIC值达到最小的成分分布个数作为混合分布的成分分布数，分布中其它参数的确定利用EM算法来估计；其次，每个成分分布对应一种主基因基因型，根据各个成分分布的均值和方差，利用正态分布的极限误差将每个个体划分到相应的成分分布中，即相应的主基因基因型中，将每种主基因型作为单因素方差分析的一个处理水平，对其进行单因素的多元方差分析，分别计算主基因效应协方差阵、多基因效应协方差阵、环境协方差阵等参数；最后结合混合分布中各成分分布的权重即各主基因基因型的分离比例，计算主基因效应方差，多基因效应方差和环境方差，以及遗传力等参数，进而计算该数量性状的遗传进展。
