Personally, I think polynomial terms higher than 2 are hard to interpret and, if they are needed, I prefer splines. But AIC and BIC (and their variants) all have fierce partisans - if you search Google, you can find many papers. But the reason software offers both choices is that neither is that the decision on which is "better" isn't in yet. | |

I do need some criterion for best. I thought that was the purpose for tools like AIC, BIC, and crossvalidation? | |
