This article estimates the extreme loss distribution with extreme value theory, estimates the shape parameter with HKKP estimator, which is unbiased to small sample data, selects the right threshold by selecting smallest mean square error of the estimated cumulative distribution function and empirical cumulative distribution function and based on the extreme value theory method, this article estimates the extreme loss distribution and the p-percentile operational loss under certain believe range for Chinese commercial banks, then calculates the operational risk supervise capital.
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。

The average percent value of G C (49.3%) was less than that of A T (50.7%), there was a bias of the content of G, T in the third codon; The number of transition G-A and T-C were 22, 15 respectively, which were higher than that of transition A-G and C-T, the number of tranversion C-A, T-G is 2 respectively, and other tranversion patterns didnt occur; the probability of transition was higher than that of tranversion , Ts/Tv = 9.5-19, there was the highest number of transition in the third codon. The gamma parameter a of the lst,nd and 3rd codon positions were 0.00572,0.01237 and 1.05239 respectively, they showed that there was adifferent substitution rate at different codon position. Frequences of synonymous codon usage were relatively biased. The average rates of synonymous and nonsynonymous substitution were 0.0787, 0.0011 respectively, there was a significant difference between dS and dN (Z = 4.713, p.01), and the low ratio( CD = 0.0284 .3) of dN/dS ratio impled that there were selective constraints against the nonsynonymous sites in cyt-b gene, The distribution of nonsynonymous codon substitution pattern related to Grantharm distance indicated that the purified selection at 2nd codon positions was more intensive than that at 1st codon positions. The phylogenetic trees supported the view of the double origin of Chinese goose, which means that domestic Chinese goose was derived from Anser cygnoides and domestic European goose, and Yili was derived from Anser anser.
碱基含量分析可知,序列的G C含量(49.3%)<A T含量(50.7%),密码子第三位点的G、T含量都有较强的偏倚性;序列间G→A和T→C的转换数(22次和15次)高于A→G和C→T的转换数(10次和9次),C→A、T→G颠换数均为2次,其余颠换模式均未发生;转换数明显高于颠换数,Ts/Tv=9.5~19,密码子第三位点的转换数最高,呈现了相当强烈的转换偏倚性;密码子第一、二和三位点的gamma分布参数α值分别为0.00572、0.01237和1.05239,表明密码子第一位点的替换速率变异最大,第二位点次之,第三位点的替换速率变异相对较小;编码同一氨基酸的同义密码子并非随机使用,表现出一定程度的使用偏倚性;同义替换速率和非同义替换速率分别为0.0787和0.0011,dS与dN值间的差异极显著(Z=4.713,p<0.01),而ω=0.0284,明显小于0.3,表明雁属鹅细胞色素b基因序列经历了中度净化选择作用;单步非同义替换(Sing-step nonsymonymous codon substitution,SSNCS)分布模式与Grantharm距离之间的关系说明密码子的三个位点所受的净化选择强度不同;构建的最大简约树与邻接树拓扑结构一致,支持中国家鹅的双起源学说,即除伊犁鹅外的其它中国鹅品种起源于鸿雁,伊犁鹅和欧洲的郎德鹅、莱茵鹅起源于灰雁。
