用到的包:MASS 提前需要明确一个问题: R和SPSS的回归结果不一定是一致的。因为R逐步回归是基于AIC指标的,而SPSS基于p值或F值。根据AIC准则,AIC值越小表明模型拟合效果越好。R逐步回归主要分为两步 第一步:lm…
stepwise multiple regression analysis,发生了会如何,不发生又会如何。stepwise multiple regression analysis的发生,到底需要如何做到,不stepwise multiple regression analysis的发生,又会如何产生。谚语在不经意间这样说过,不幸可能成为通向幸福的桥梁。带着这句话,我们还要更加慎重的审视这个问题:了解清楚stepwise multiple...

This chapter describes how to perform stepwise logistic regression in R. In our example, the stepwise regression have selected a reduced number of predictor variables resulting to a final model, which performance was similar to the one of the full model. So, the stepwise sele...
