After comparing the two type of tests,we came to some conclusions.The tests based on binomial test can be regarded as some kind of permutation tests under certain definition of "permutaton".If the tests are related to statistics,then whether they can be viewed as permutation tests depends on if the value of the probability,p,is known where p is the population parameter in the null hypothesis.For tests like Kolmogorov goodness-of-fit test,since the statistics is calculated based on empirical distribution function,hence no matter how we repermutate the observations,the order statistics is the same.This kind of tests can't be regarded as permutation tests.
我们得到的结论为:在一般的无母数检定中,如果检定与binomial test相关,基本上都可以视作排列检定的一种;与卡方检定相关的检定,基本上和p值已知或是未知有关,这个p值为原始假设下所要检定的母体机率值;其他检定如Kolmogorov goodness-of-fit test,由於统计量的值是根据empirical distribution function决定,而不论如何重新排列样本,其顺序统计量都不变,所以无法视为一种排列检定。

Then,we improve CSFP Model in two aspects:when we ascertain the frequency of default,we use negative binomial distribution to substitute Poisson distribution so that the model can measure the data better;when we ascertain the loss distribution of default,we use Γ-distribution to substitute normal distribution.
其创新与特色一是对贷款组合的风险暴露数进行分段,在每一频段上分别确定风险暴露数分布,进而可以更准确的描述各笔贷款的风险暴露数。二是在确定风险暴露数分布时,用Γ分布替代了传统的正态分布,解决了贷款违约的风险暴露数分布的厚尾问题,进而解决了大宗贷款违约的风险度量问题。三是确定违约频率时,用负二项分布来代替传统的泊松分布,解决了违约频率的方差通常要大于其均值的分布拟合问题。

We obtain the risk process involved in this model,the statistical properties of the surplus process,and statistical features of the claim numbers and the probability distribution of the total amount of compensation.The three types of business of the risk model is given when the number of claims obey Poisson distribution and negative binomial distribution.We make a comparison between the risk model built in the thesis and the classic risk models with independent claim numbers when the amount of claims obey Weillbull distribution and Exponential distribution.The results have a good practical significance.
其次,考虑不同险种间的相互关系,建立了一种含有主副理赔的风险分析模型;借助随机过程和经典风险理论,对该风险模型所涉及的风险过程、盈余过程的统计特性以及理赔总额的概率分布、数字特征和矩母函数进行解析研究,给出了主理赔次数服从泊松分布和负二项分布的这种风险模型的具体实例,并在理赔额变量服从Weillbul分布和Exponential分布的情况下,把文中所建风险模型和理赔次数相互独立的风险模型作了比较,所得结果有很好的现实意义。

I have calculated the species diversity for 3 layers (i.e. tree layer, shrub layer and herb layer) by means of various biodiversity index formulas and analyzed the relative species abundance using 9 models of the probability density distribution functions, such as, 3 Distribution (or Beta Distribution, Weibull Distribution, Lognormal Distribution, Poisson Distribution, Binomial Distribution, Negative Binomial Distribution ,Geometric Distribution, etc.. chi-square analyses were conducted on species distribution by using the chi-square test formulated by Pearson to test which distribution function is better, the result of chi square test made it possible to reject the other 8 distribution functions, theβdistribution function performs better than other probability density functions, it has a very close approximation, which can be used for the description of relative abundances of species in forest communities in this data set.
在相对多度研究上选用了九种概率分布模型,这九种概率密度分布函数依次为:贝塔分布、Weibull分布、对数正态分布、泊松分布、二项分布、负二项分布、几何分布、对数分布和奈曼A型分布,并进行了严格的卡方检验,结果表明:其它八种分布均被遭到拒绝,只有贝塔分布获得了通过,且拟合的结果非常理想。
