方差估计值 meaning in Chinese
estimator of variance
Examples
- Allan variance estimated by simulated noise and calculated theoretically using power law model are well matched . the effect of phase noise on azimuth focusing is given by monte carlo experiment
模拟相噪得到的allan方差估计值与幂律模型得到的allan方差理论值符合得较好。 - The complex system reliability mean and variance can be obtained based on component reliability information and the condition that the complex system can be decomposed into series or parallel systems
在获得单元可靠性的均值和方差的基础上，利用系统可以分解为单一的串联或并联关系，通过逐步综合获得复杂系统的可靠性均值和方差估计值。 - The adaptability of the national sugarbeet variety test in 2002 was analyzed through statistical parameter of variance and coefficient of variability from variety locus of test data
摘要通过对2002年国家甜菜品种区城试验结果的统计分析，求得各参试品种的适应性统计参数品种地点互作方差估计值和变异系数，据此对参试品种进行适应性分析。 - Firstly , we estimate the variance and the mean of each cell with maximum likelihood ; secondly , we identify the important dispersion effects based on least squares analysis of the logarithm of within - replication variance ; last , we identify the important location effects based on weighted least squares analysis of the mean of each cell . a simulation study also demonstrates its superiority over some existing methods . an experiment for the robust design of thermostat is used to illustrate the method
本文对带有右截尾数据的有重复因子试验，提出了另一种分析位置效应和散度效应的方法：首先，在每一个试验点，对重复试验观察值用极大似然法估计出均值和方差；其次，用每个试验点方差估计值的对数作为响应变量与各因子建立回归模型，鉴别出显著的散度效应；之后，采用加权最小二乘法鉴别出比较显著的位置效应。
