[R] stepAIC

[stephenc]

Hi

 

I hope this isn't off topics, but I have always found when I stepAIC() some
glm I get an improvement in accuracy and kappa, but I have just done a case
where I got a marginal deterioration.  Is this possible, or should I be
going through my figures carefully to see if I have messed up?
