术语“全部子集回归”的详细信息

英译术语:

all subsets regression

汉语语境:

应用回归分析处理实际问题时，选择适当的回归自变量是一个十分重要的问题。逐步回归方法是一种常见的选择回归变量的算法。但由于这种方法并不计算所有可能的变量自己的回归，并且每次选或剔除一个变量时，要做一次F检验，而事先确定的显著性水平直接影响到最后的回归子集，所得到的可能是全部子集回归。

英语语境:

Regression analysis dealing with practical problems, choose the appropriate return argument is a very important issue. Stepwise regression method is a common algorithm to select regression variables. But this method does not calculate all possible variables their return, or removed every election or when a variable, do a F test, and a pre-determined level of significance directly affect the final regression subset obtainedIt may be all subset regression.
