Actually, the results of goodness of fit vary distinctly across different fitting methods.

事实上，不同的检验方法得出的模型的拟合优度有着明显的差别。

Finally, the wind velocity data of Nantong observatory are used to verify the methods above-mentioned, and the likelihood ratio method and Kolmogorov statistic are used to test the fitness of the distribution, It is obtained that the distribution of yearly extreme wind velocity of the observatory is in keeping with Frechet distribution, and the experimental distribution form from samples basically coincides with the theoretical ones.

采用南通气象观测站的年最大风速资料进行实证研究，分别用似然比法和Kolmogorv统计量检验分布的拟合优度，得出南通气象观测站年最大风速符合Frechet分布，而由样本值构造的经验分布与理论分布曲线基本相吻合。

Finally, the physical index and compression index of silty soil from Yangtze Basf project are divided to three groups according to depth, then characteristic statistic are calculated to physical and compression index of three groups and mechanical index of all depths. After that, normal distribution 、 logarithmic normal distribution and extreme I distribution are fitted for physical and mechanical indexes. And Goodness-of-fit testing with X~2 method is done subsequently.

最后，将扬子巴斯夫工程粉质粘土的物理指标和压缩性指标按照埋深分为三组，计算了不同深度上粉质粘土的物理指标和压缩性指标以及所有深度上抗剪强度指标的特征统计量；然后用正态分布、对数正态分布和极值I型分布对各指标进行概率模型拟合并用x~2法对拟合优度进行了检验。

Firstly, reviewing and commenting on foreign and domestic literature about nonrecurring gains and losses; secondly, analyzing the definition and characteristics of nonrecurring gains and losses and the reason to form nonrecurring gains and losses; following, examining the research hypothesis using descriptive statistics and correlation analysis and regression of price and return model, furthermore optimizing the price model and return model through adding year variable and district variable which was divided according the return of the extraordinary items as dummy variables in the empirical research part.

文章先对国内外关于非经常性损益的研究现状进行回顾与述评；其次对我国关于非经常性损益的界定及其形成动机进行了分析；紧接着实证部分采用描述性统计、相关分析和运用价格模型和收益模型进行回归分析，对本文提出的研究假设进行检验，并加入年度虚拟变量和按照非经常项目利润率进行划分的区间虚拟变量对价格模型和收益模型进一步优化，使线性回归方程的拟合优度R2得到显著提高，利用优化后的模型对研究假设进一步检验。

aim: to generate random sequences that can fit the anticipated probability distribution based on the thinking of mc, methods: we establish a method in the ide of visual studio by the way of linear congruential method to generate random sequences.we also test the homogeneity and independence by the chi-sqare goodness of fit test and self-correlation test.

v+\$oXb；L^7h_0 目的：基于mc法生成符合预期概率分布的随机序列，以便应用在以后的仿真系统中。方法：应用线性同余法在visual studio环境中建立随机模型模拟随机序列生成。并采用χ2拟合优度检验法和自相关检验法检验生成的随机序列的均匀性、独立性。

The Hardy-Weinberg equilibrium for genotypic distribution was estimated by the goodness-of-fit test. The UNPHASED program was applied to perform the transmission disequilibrium test, the haplotype analysis and the pair-wise measure of linkage disequilibrium between these 2 SNPs.
