Description: 逐步回归的基本思想是有进有出。具体做法是将变量一个一个引入，当每引入一个自变量后，对已选入的变量要进行逐个检验，当原引入的变量由于后面变量的引入而变得不再显著时，要将其剔除。引入一个变量或从回归方程中剔除一个变量，为逐步回归的一步，每一步都要进行 检验，以确保每次引入新的变量，之前回归方程中只包含显著的变量。这个过程反复进行，直到既无显著的自变量选入回归方程，也无不显著自变量从回归方程中剔除为止。-the basic idea is out there Progressive. Specific approach to the introduction of a variable one, every since the introduction of a variable, the right has been elected to the variables for each test, When the original due to the introduction of variable behind the introduction of variable is no longer significant, and should he be removed. Introduction of a variable regression equation or removed a variable, for the gradual return of the step, every step must undergo inspection, to ensure that each introduction of a new variable, before regression equations contain only significant variable. This process repeated until no significant variables into the equation election, are all significant variables from the regression equation far removed.

Description: 回归分析中，检验自变量的重要性，将变量一个一个引入引入变量的条件是其偏回归平方和经检验时显著的，在引入新变量的同时，对已入选的变量逐个检验，将不显著的变量剔除。-The importance of the independent variables of regression analysis, test, introducing variable is introduced one by one into the condition of variable is the partial regression sum of squares in significantly after inspection, and at the same time of introducing new variables, for the selected variables one by one test, will not be significant variables.
