Re: [R] how 'stepAIC' selects?

Hi Veronika, StepAIC does not do any test. But you may do a likelihood ratio test on the difference between deviance of two models to judge which model to use, simply like this, 1 - pchisq(deviance.i - deviance.j, df.i - df.j) And then check whether the returned p value is small enough...
