Hi Elaine, in general, stepwise selection is a very bad idea:
Whittingham, M. J.; Stephens, P. A.; Bradbury, R. B. & Freckleton, R. P. Why do we still use stepwise modelling in ecology and behaviour? Journal of Animal Ecology, 2006, 75, 1182-1189

Dear list, I wanna select the significant variables relative to bird distribution, using stepwise method. However, the result is always the best-fit model. Please kindly suggest if it is possible to show the selection process.
