Thanks for the response, Frank.
I am not saying that I want to delete a variables because of p>0.5. But my
concern was: I am using backward stepwise logistic regression, it keeps the
variables in the final model if the variable significantly contributing in
the model. Otherwise, it should not be
What would make you want to delete a variable because P > 0.05? That will
invalidate every aspect of statistical inference for the model.

Hi R user,
I am a kind of an intermediate user of R. Now I am using GLM model (library
MASS, VEGUS). I used a backward stepwise logistic regression, but i got a
problem in removing those predictors which are above 0.05. I don't want to
include those variables which were above 0.05 in final backw
