Dear all,
Could anyone please tell me how 'step' or 'stepAIC' works? Does it simply select the model with the smallest AIC from all the possible
models? Or does it perform any test eg. whether the decrease in "information content" between a model with a given predictor and another without it is "significant"?
Thanks for help!
