抽样分布

Analysis for adaptability of MWSN s longevity by genetic algorithm of bestrew distributing

本文就产品特征服从韦布分布的情况，建立了一类计量抽样检验方案，并求出其OC函数。

In the first stage, we assume that the probability that a given team wins is a random sample from a beta distribution with parameters based on the relative strength variable and the home field advantage variable.

在第一阶段中，我们评估队伍得胜的概率是来自一个参数基於相对实力变数与主场优势变数的beta分布的随机抽样。

Binomial distribution is preferred in testability demonstration,but it is discrete.Because of calculation difficulty,the sampling plan is usually worked out with some adaptations.

在测试性验证中首选的二项分布是离散取值的，由于计算困难，确定抽样方案通常采用一些变通的方法。

In the context of signal processing it is often referred to as the unit impulse function. Note that the Dirac delta is not strictly a function. While for many purposes it can be manipulated as such, formally it can be defined as a distribution that is also a measure .

在物理上，通常用于代表脉冲函数，或者呈点分布的物理量，例如质点、点电荷等；另外，delta函数常用于表示对物理量在某点的抽样，这一点不仅在数学物理方法这样的理论学科中常用，在实际的工程通信中也很常用，这时delta函数被用作采样函数。

Chapter six presents a two-waves sampling method to estimate a distribution function of a discrete random variable Y.

第六章研究在数据缺失机制形式未知时，通过两步抽样得到了分布函数的相合的估计量，且该估计量是渐近正态的。

From statistics, the theorem that the distribution of sample means taken from a large population approaches a normal, Gaussian, curve.

根据此定理，统计抽样的样本量越大，则随机选择的样本平均值越接近于正态分布。

Methods According to the example given,rate ratiomodel was constructed and simulated with Latin Hypercube Sampling.

结合实例进行相对危险度的模型构建、拉丁超立方抽样和概率分布的拟合及RR可信区间的几种计算方法比较。

Uniform random sampling is widely applied to many kinds of algorithms in data mining. It processes uniform distribution data set extremely effectively, but easily loses slight cluster and consequently decreases clustering accuracy, when the processing data set is skew distribution.

随机抽样技术已经广泛应用于数据挖掘的各类算法中，它在处理分布均匀的数据集时非常有效，但在处理分布比较倾斜的数据集时容易丢失小的聚类。

By an imaginary uniform sampling on the original triangle mesh, our algorithm makes the 3D point set using in ICP algorithm not only approximatively uniformly distribute in the measured object surface, but also possess of more information of the object surface than classical ICP algorithm.

通过在三角形网格上按面积均匀分布的假想抽样，在没有明显增加计算复杂度的情况下，使得代入ICP算法的3D点集，不仅是近似均匀地分布在物体表面上，而且更加充分地反映了被测物体的表面信息。

In March to middle of June of 2004,fifty random selected nests of Phalacrocorax carbo in Majuan Island of Sanjiang National Nature Reserve of Haiqing town of Fuyuan county of Heilongjiang province were numbered and measured one by one to study the materials,location and direction,and size of the nests.

2004年3~6月，在黑龙江省三江国家级自然保护区海青保护站马圈岛，采用随机抽样法，对随机选取的50个普通鸬鹚巢逐一进行编号和测量，进行巢材、巢位和巢大小等的研究；采用总面积调查法(样方大小为30m×30m)，对普通鸬鹚巢的分布格局、分布特点进行了研究。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
