随机样本 meaning in English
chance sample
random sample
Examples
- You can test package execution and data transformation with richly representative data , but more quickly because a random sample is used instead of the full dataset
这样，您就可以使用很有代表性的数据来测试包执行和数据转换，而且这种测试更加快捷，因为它使用的是随机样本而不是全部数据集。 - Through proper sampling design , the selected households for march and the first half of april together formed a separate and scientific random sample by themselves and data collected on them could be used to draw inference on the overall situation
透过恰当的样本设计，三月至四月中的访问住户，组成一个独立的科学性随机样本，所搜集得的资料可以用来推论整体的情况。 - Idea : we cannot measure the closeness of the estimates with the population parameter directly , but it is possible to use data from a random sample to construct a set of values that contains the true value with a certain specified probability
我们无法直接衡量估计值和总体参数之间的距离，但是利用来自随机样本的数据构造一个取值的集合，使得真值在给定概率下属于这个集合是可能的。 - The qualification of multipactor and the characteristic of the angle and velocity of secondary electron were study . bring forward a improved model of multipactor and solve it by a random sample made by monte carlo , as a result , a critical curve of multipactor was gained
提出了一个改进型的次级电子倍增研究模型,利用蒙特卡罗法生成的随机样本来求解这个模型,得到了工作在2 . 85ghz的介质片的次级电子倍增敏感度曲线。 - Abstract : a fuzzy and random method for estimating the three parameters ofweibull distribution was put forward . the method was tested and verified by the random samples obtained by monte carlo method . and the results showed that the estimating values of the parameters are close to the theoretical value
文摘:提出了威布尔分布三参数估计的模糊?随机方法，并对蒙特卡罗方法产生的随机样本进行了验证；结果表明，求得的参数估计值十分接近理论值。
