汉英语境1
英译术语:
principal component analysis
汉语语境:
统计推断作为现代统计学的基本方法，在统计研究中得到了极为广泛的英勇，它既可以用于对总体参数的估计，也可以用作对总体某些分布特征的假设检验。主成分分析方法是一种应用十分广泛的多元统计分析方法，在主成分分析中，往往难以直接导出总体主成分，因此，需要用样本主成分去估计总体主成分，这就涉及到的主成分分析中的统计推断问题。
英语语境:
As the basic method of the modern statistics, statistical inference is widely used in statistical research. It can be used either for the overall parameters estimation, or can be used in some of the overall distribution characteristics to test the hypotheses. The principal component analysis is a very widely used method of multivariate statistical analysis. In the principal component analysis, it is usually difficult to derive a total principal component directly. Therefore, it needs to use the sample to estimate the main component of the overall principal components. This is related to statistical inference problems in the principal component analysis.
