need a clarification on logistic regression
...nteractions of variables should be constructed in this way ? :
> rsat2=glm(cbind(landp,landa) ~
as.factor(rlito)*as.factor(rslp)*as.factor(rasp)*as.factor(rplc)*as.factor(rwi),family=
binomial(link=logit),data=rdf46)
then
using stepAIC to eliminate some models having high AIC values.
> stpAIC_r2=stepAIC(rsat2,list(lower=~1,upper=formula(rsat2)),trace=F)
But obtained final model looks very intricate and I couldn't interpret it.
> stpAIC_r2$anova
Do I have to consider last line (13) ?
