方差分量估计方法 的翻译结果

: "setup failed. use the following links to research the source of the failure: there were errors during setup. although the components were installed successfully, some setup errors were detected. view error log。chronyd provides support for isolated networks where the only method of time correction is manual entry. for example, by the administrator looking at a clock. chronyd can examine the errors corrected at different updates to estimate the rate at which the computer gains or loses time, and use this estimate to trim the computer clock subsequently. 。incremental compilation means that only components that were touched since the last compilation, and their dependencies, are recompiled. incremental compilation can be significantly faster than a full compilation when changes are limited to only a limited set of components.。

与赫尔默特方法进行了比较,结果表明,有粗差时,方差分量估计和参数估计结果随着Lp估计的p的变化相差显著,无粗差时(或粗差被剔除时),不同的方差分量估计方法的结果相差甚微。

variance component estimation

Variance component estimation techniques compared for two mating designs with forest genetic architecture through computer simul

Merr.) breeding program and applied a mixed-model approach that comprised three steps: variance component estimation, single-marker analyses, and multiple-marker analysis.

The methodology involved three steps: variance component estimation, single-marker analyses, and a final multiple-marker analysis with marker effects treated as fixed effects.

The concept of variance component estimation is also proposed as an important statistical tool for assessing the actual gravimetric geoid noise level and/or testing a priori determined geoid error models.

However, most of the methods proposed so far for variance component estimation involve repeated inversion of large matrices, resulting in intensive computations and large storage requirements if more than a few hundred unknowns are to be determined.

In this paper, stochastic model error and its influence on the results of combinedsatellite and terrestrial net adjustment are discussed. A method of variance-component-estimating (VCE) has been applied to combined adjustment. Some numerical of analo-gous and real observations are given, which are discussed.

本文讨论了卫星网与地面网联合平差中随机模型误差及其对联合平差结果的影响,应用方差分量估计方法对卫星网和地面网的随机模型进行了估计,并对模拟网与实测网的计算结果进行了分析。

The variance components estimation method is used to handle the data of EDMI measurements. Firstry, to find the weights of observations, then, solving for the imstrument's additive constant K, and multiplying constant R, fixed error coefficient a and proportional error coefficient b. This is an attempt to determine the wcights'ratio of the same kind observations with different accuracies.

本文应用方差分量估计的方法,在对光电测距仪的检测成果进行数据处理时,首先求得观测值的权,然后解算仪器的加常数K,乘常数R和固定误差系数a,比例误差系数b的数值,它是用于确定同类观测不同精度观测值之间权比的一个尝试。

A unified Variance components estimation in the Gauss-Markov model with a singular covariance matrix of observations and singular design matrix is discussed in this paper. The derivation of formula is simple, and need not to solve the linear equations. The non-negtive requirement of iteration is also satisfied. As a special case, the comparisons to Helmert and MINQUE estimation are studied. Finally, a example of EDM error analyses is given.

smith和murray将方差分量作为协方差，并使用基于二次形式的anova程序从平衡数据估计它们.green将完成对不平衡数据的该公式.goldstein引入迭代重新加权的一般化最小二乘法。2、预留膨胀空间，膨胀空间大小可由下列公式计算：膨胀值=线性膨胀系数×长度×最大温度变化值线性膨胀系数为固定值=7×10-5(cm/cm/℃)实例：长度100cm的pc板方差分量估计，安装在昼夜温差40℃的环境中，则其预留膨胀空间为：膨胀值=7×10-5(cm/cm/℃)×100(cm)×40℃=0.28(cm)故预留膨胀空间至少要0.28cm。 = =一元线性回归的统计分析1. 误差方差d &epsilon。
