例句与用法
- The application of subpopulation estimation method in business valuation
子总体估计法在企业价值评估中的应用 - The gwm model for splice signals is a mixture of weight matrix models ( wmm ) with unknown number of components
分组权重矩阵是一个子总体数未知的混合权重矩阵模型。 - For computation of the unknown parameters ' mle , the em method is applied ; and the number of components is determined by using the gap statistics
为得到未知参数的极大似然估计,采用了em方法,而子总体数是利用隙统计量确定的。 - But as an very ideal situation , hardy - weinberg equilibrium is not always suitable . for example , if we take the uncertainty which arise from population substructure it ' s not suitable
但是考虑到一些不确定性因素如人口子总体的情况,那么这时hardy - weinberg平衡不成立。 - At first , the population sample data are split into subpopulation data sets over the whole test duration by using the posterior belonging probability of each observation to each subpopulation
利用对每个子总体的每次观察的后验概率将整个检验期间的总体样本数据分成子总体数据集。 - First , this paper gives an introduction of some methods of unequal probability sampling , their estimators and variance estimators , including sampling with pps with replacement , methods of sampling without replacement suggested by brewer , durbin , sampford , des raj , murthy , rao - hartley - cochran . then , at the basis of rao and bayless ' s study , we consider that population can be splited two random subpopulations , which are respectively drawn from different infinite super - populations , and compare the stabilities of estimators of the methods that given above . we find that the minor difference between two super - populations has great effect on the efficiency of the estimators for the population with moderately large coefficient of variation ( c . v . )
本文首先从理论上介绍了若干种不等概率抽样方法,它们的估计量、估计量的方差及其估计,其中包括有放回ppz及pps抽样,不放回不等概率抽样中的brewer 、 durbin 、 sampford 、 desraj , murthy 、 rao - hartley - cochran等人的方法;其次,在rao和bayless两人就样本单元数n = 2的情形对上述抽样方法进行比较的基础上,将总体随机地分成两个子总体,视每个子总体取自不同的线性超总体,在文中,我们利用计算机实现随机分组,并通过画图比较各方法估计量的稳定性,结果表明,对变异系数c . v . ( x )较大的总体而言,两个超总体之间的微小差异将对估计量的稳定性产生很大的影响,从而说明rao和bayless的比较结果还不够完善。 - Then , with the concept of accumulated failure probability , the proposed approach combines the least ? quares method with bayes " theorem , takes advantage of the parameter estimation for single weibull distribution to each derived subgroup data set , and estimates the parameters of each subpopulation . the estimates given by this paper also satisfy the maximum likelihood equation . the mean time to failure and the reliability estimation of the mixed population are given
