variance component

基本解釋

The genetic parameters of major quantity traits of white feather muscovy duck RF line were estimated with variance component of the mixed family.
采用混合家系方差組分剖分法對(duì)白羽番鴨RF系的主要經(jīng)濟(jì)性狀遺傳參數(shù)進(jìn)行了估計(jì)。
Methods We applied generalized linear mixed models for the nuclear family data to set up the genetic variance component model and estimated parameters using MCMC.
將廣義線性混合模型應(yīng)用于核心家系資料建立遺傳方差分量模型，運(yùn)用MCMC方法進(jìn)行參數(shù)估計(jì)。
Methods:Based on the characteristics of hierarchical structure in the development toxicity study data, exploring the application of two level variance component models.
方法：根據(jù)發(fā)育毒性實(shí)驗(yàn)研究資料存在層次結(jié)構(gòu)的特點(diǎn)，探討了兩水平方差成分模型在此類資料中的應(yīng)用。

方差分量
Variance component estimation is a good method to resolve the problem. So the dissertation researched how to apply Helmert variance component estimation into GPS network adjustment, according to adjusting the baseline vectors’ weight to increase the precision.
本文研究了將Helmert方差分量估計(jì)方法應(yīng)用于GPS網(wǎng)平差,通過調(diào)整單位權(quán)中誤差,重新定權(quán),使不同類型觀測(cè)值之間的權(quán)比達(dá)到合理配置,提高平差精度。
