Forward selection(前向选择) 方法介绍 From 《商务与经济统计》第十三版 P416 前向选择方法从模型中没有自变量开始。 这一方法使用与逐步回归为了确定一个变量是否应该进人模型同样的程序来增加变量,并且一次只能增加一个变量。然而,一旦一个自变量进入到模型中,前向选择方法就不允许再将这个变量从模型中删除。当不...

This paper uses the unconditional mean square error of prediction as a criterion for comparing stopping rules used with the forward “stepwise” selection procedure in multivariate normal samples, based on simulations of 48 population correlation matrices. The CP statistic, “F to enter” (.15 < ...
The article presents a proposal of a new method for variable selection in Data Envelopment Analysis (DEA). The method is based on stepwise adding of variables to a simple (one output/one input) model. Two conditions are used to recognize which variable should be added to the model: relative...
