Hi, I would like to uses AIC.c criterion in stepwise selection. I found some comments about this issue in R help archives, and it seems that no standard scripts are available. Except from www.prodsyse.com (stepAIC.c), but, unfortunately, demanding adaptations for R. Suggestions on this will be very much appreciated regards Flavio Zanini

stepAIC uses extractAIC to calculate AIC. So all that is in principle necessary is to modify extractAIC to return AICc.
