查询词典 population parameter

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 statistics, a confidence interval is an interval estimate of a population parameter.

在统计学里，置信区间指的是对于某一群体参数的区间估计。

In order to think about unbiasedness, we need to rewrite our estimator in terms of the population parameter

为了考虑无偏性，我们需要用总体的参数改写

The standard error of a statistic provides an indication of how accurate an estimate it is of the population parameter.

统计量的标准误差表示该统计量作为总体参数的估计的准确程度。

We cannot accept or reject a hypothesis about a population parameter simply by intuition.

我们不能只凭感觉简单地决定接受或拒绝总体参数的某种假设。

A population parameter is a constant, unchanging value estimated from a sample statistic.

母体 参数是一个持续不变的由统计样本推算出的值。

Parameter estimate lays particular emphasis on individual population parameter of model in the past. Its common purpose aims at seeking one method to optimize parameter in the equation.

以往参数估计研究都侧重于单个种群模型中的参数确定，其共同的目的旨在寻求一种使方程中参数达到最优化的方法。

According to the quality of HT statistics, we know that the sampling structure after adjusting is relatively closed to that of population. The accuracy of the population parameter inferred through this statistic will be higher than that have not considered the influence from background.

在确定出对核心问题回答有影响的背景因素之后，我们应用Horvitz Thompson统计量对抽样调查的数据作适当调整，由Horvitz Thompson统计量的性质，我们知道经过处理后的样本结构比较接近总体结构，由该统计量推断出的总体参数的精度比不考虑背景因素影响条件下的精度更优。

A point estimate may be the researcher's best guess at the population value, but, by its nature, it provides no information about how close the estimate is "likely" to be to the population parameter.

点估计本身并不能告诉研究者该估计值和总体参数的距离到底有多近。

For a given proportion p (where p is the confidence level), a confidence interval for a population parameter is an interval that is calculated from a random sample of an underlying population such that, if the sampling was repeated numerous times and the confidence interval recalculated from each sample according to the same method, a proportion p of the confidence intervals would contain the population parameter in question.

对于一个比例 P而言，一个群体参数的置信区间中的区间是由一个基础群体的随意样本计算出的，假如样本被重复了无数次，置信区间也根据每个样本，以同样的方法重新计算，那么这个置信区间中的比例 P 将要重新定论。

He is the most remarkable man that I have ever known.

他是我知道的人中最值得注意的人。
