In this paper wecalculated the cross-section ratios of associate η_c +γ productionin the p-p and p-Au collisions and found that this process is connected closely with the nuclear gluon distribution function. Bystudying the associate η_c +γ production in high energy p-Aucollision, we can know more about the nuclear gluon distribution function.

Firstly, we test that the error data are not normal distribution, and even the expectation is not zero. Then we analyze the possible type distribution of these error data. Finally, we use the stepwise method to fit the error data and obtain a function for some parameters of the SAIL model. As prior knowledge, the fitting function will be used to inverse these parameters ofthe SAIL model soon.

首先检验了误差数据不服从正态分布，甚至均值不为零；然后对误差数据可能服从的分布类型给予了解析，得到了指数分布和混合正态分布两种不同类型的可能分布；最后拟合了误差关于SAIL模型部分参数的函数表达式，以作为先验知识应用于反演之中。

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。
