AICとBIC、どっちを使うか?

両方使う。表の一列 (行)が増えるだけ

  AIC BIC
 Is your analysis exploratory analysis? confirmatory analysis?
 Is the analysis open-ended? a few specific models representing a well understood process being compared?
 As the dataset gets larger, do you expect your model to grow in complexity?  stabilize? 
 Do you believe you have chosen the correct functional form of the relationship as well as the correct variable? No  Yes 
 Is your goal accurate prediction?  finding the correct model?
