查询词典 variance

Severe multicollinearity means the variance of the estimated parameter will be very large.

严重的多重共线性意味着被估计参数的方差将非常大。

But it is worth remembering that when these variables are available, they can be included in a model to reduce the error variance without inducing multicollinearity.

作为一个原则需要记住：总可以将此类变量包含进模型，如果他们存在。

The sampling of complicated materials were investigated. The relationship between the composite sampling variance and the number of increments was studied. The quantitative equation for estimating the composite sampling errors directly from the physical and chemical parameters of the population with multinomial distribution theory was presented. Monte Carlo simulation technique was employed to verify the above theories.

对于复杂物质的取样，研究了分层性物质的组合取样误差与份样数目之间的关系；采用多项分布理论，提出了组合取样误差公式，建立了组合取样误差与被研究总体的理化参数(如组分含量、质量分数等)之间的定量关系，通过Monte Carlo模拟技术对此进行了验证。
