Pareto optimal linear classification
Linear classifier probability weigh gaussian distribution
2015/8/10
We consider the problem of choosing a linear classifier that minimizes misclassification probabilities in two-class classification, which is a bi-criterion problem, involving a trade-off between two o...
极值理论主要研究小概率、大影响的极端事件.当前,复合极值分布已经广泛应用于水文、气象、地震、保险、金融等领域.本文以极值类型定理和PBDH定理为理论依据,构建了二项-广义Pareto复合极值分布模型;使用概率加权矩方法,对所建立的复合模型推导参数估计式;利用计算机模拟,得到了Kolmogorov-Smirnov(简称KS)检验统计量的临界值.
广义Pareto分布的广义有偏概率加权矩估计方法
广义Pareto分布 广义有偏概率加权矩估计 次序统计量 截尾样本 概率加权矩估计
2013/10/19
广义Pareto分布(GPD)是统计分析中一个极为重要的分布,被广泛应用于金融、保险、水文及气象等领域.传统的参数估计方法如极大似然估计、矩估计及概率加权矩估计方法等已被广泛应用,但使用中存在一定的局限性.虽然提出很多改进方法如广义概率加权矩估计、L矩和LH矩法等,但都是研究完全样本的估计问题,而在水文及气象等应用领域常出现截尾样本.本文基于概率加权矩理论,利用截尾样本对三参数GPD提出一种应用范...
本文从联合保险市场Pareto最优风险转换出发,考虑保险公司不仅是分出再保险自己公司承保的风险,也可以分入再保险以分保其他公司的风险,整个保险市场的各公司之间是相互承保的,形成一个联合共保的市场整体,依据Borch的市场均衡理论,建立了保险公司之间联合比例分保模型,同时给出了风险转移矩阵的基本性质、各保险公司的安全荷载系数、各公司之间相关度以及各保险公司的破产概率,最后给出了有关联合共保及Pare...

Shannon entropy for the Feller-Pareto (FP) family and order statistics of FP subfamilies
Burr distribution Entropy Feller-Pareto distribution
2010/9/20
In this paper, we derive the exact analytical expressions of entropy for the FellerPareto(FP) family and order statistics of FP subfamilies. The FP family is a very general unimodal distribution which...
By using the definition of the ”Pareto minimum solution” of an inconsistent system, we will find in the paper a connection between this notion and the so-called ”infrasolution” of a such kind of syste...
