查询词典 empirical distribution function

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。

In real calculation, what we should do is just using empirical distribution function to replace real distribution function.

在实际计算中，我们只需用经验分布函数F_n~*来代替真实分布函数F即可。

And the probability can be approximated by the empirical distribution function evaluated at , an estimator of is given by

From the empirical distribution function,a new algorithm of the distribution function is obtained by using the theory of the spline function.

由经验分布函数出发，利用样条函数理论，给出构造分布函数的一种算法。

However,the image of the two density function are similar,so the images of their distribution function and empirical distribution function are similar too.

对于一组来自χ2分布或F(m1，m 2)分布的数据，用通常的作经验分布函数图像的方法，难以区分这组数据到底来自哪一个总体。

For a group of data collected from χ2 distribution or F distribution,it is difficult to judge where they are from if use the usual way of making image about empirical distribution function.

提出了用假设检验的方法判断一组来自χ2分布或F(m1，m2)分布数据是服从χ2分布还是服从F(m1，m 2)分布。

The next two chapters are the main content. From empirical distribution function, using theory of spline function , give new algorithms of monad distribution function and multivariate distribution function separately.

第三章和第四章由经验分布函数出发，利用B—样条函数理论，分别给出构造一元分布函数和多元分布函数的方法。

Choosing reliability simulation data as a sample, the parameter confidence interval as coding space and the reciprocal of errors between empirical distribution function and acquired distribution function as a fitness function, the point estimation model of age distribution is established based on the genetic algorithm, and the reliability function of complex systems is acquired.

以可靠性仿真数据为寿命样本，待估计参数的置信区间为编码空间，以经验分布与所求分布误差倒数为适应度函数，建立了基于遗传算法的寿命分布参数点估计模型，求得了复杂系统可靠度函数。

The results show that both the incidence and prevalence rates are increasing over 1996 to 2003; the incidence rate, prevalence rate, survival function, mean onset age, and mean remaining life after onset of females are all larger than those of males. In addition, females are less biologically aged than males at the same chronological age by 1.3279 years in terms of the empirical distribution function of onset age.

研究结果显示，首发率和盛行率皆有逐年上升的趋势，而女性患者之首发率、盛行率、存活机率、首发后之平均余命皆高於男性；此外，若单纯以男、女性患者之首发年龄而论，其经验机率密度函数显示：男性患者之生理年龄比同年龄的女性患者早衰1.3279岁。
