查询词典 population statistics

We discuss asymptotically best linear unbiased estimators of the Logistic population based on selected order statistics and give the formula of computing the ABLUE, the variance and the covariance of the ABLUE in limit, and properties of the ABLUE, and so on. We give the optimum chosen of spacing which is the ABLUE with maximum asymptotic relative efficiency based on complete sample when selected order statistics number is less than 10, and obtain its maximum asymptotic relative efficiency.

讨论基于Logistic总体Ⅱ型截尾样本的若干个样本分位数的总体分布参数的近似最佳线性无偏估计；给出了该近似最佳线性无偏估计的计算公式，估计方差与协方差的极限表达式及估计量的大样本性质等；给出了全样本，样本分位点个数固定，但不超过10情形下，使上述近似最佳线性无偏估计有最大相对联合估计效率时，样本分位数选取法及最大相对联合估计效率；为大样本情形下，该近似最佳线性无偏估计的应用提供了理论依据。

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。

We point out the similarity and difference between the properties of the order statistics from the geometric distribution population and exponential distribution population.

And human resources information's management is many factories and mines, the company, an individual Institution's major problem, if depends on the human, the work load will be very big, if the company population has tens of thousands are even more, the artificial statistics will become cannot imagine, but if depends on the computer, only some simple operations then may prompt, obtain the information which accurately needs, therefore develops a human resources information management system management system is also essential, the human resources information management system management system mainly includes to the human affairs information statistics, the inquiry, the renewal and so on, this paper has manifested the database application system's characteristic, enables the system to have the security, data sharing, the transposability.

其中人才信息的管理是很多厂矿、公司、个体事业单位的一个大问题，如果靠人，工作量将很大，若公司人数有几万甚至更多，人工统计将变得不可想象，但如果靠计算机，仅一些简单的操作便可及时、准确地获得需要的信息，因此开发一个人才信息管理系统也是必不可少的，人才信息管理系统主要包括对人事信息的统计、查询、更新等，该论文体现了数据库应用系统的特征，使系统更具有安全性、数据共享性、可移置性。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it.
