lm -- significance of x coefficient when I(x^2) is used
...significantly different from 0 and that I had better set it to 0, i.e. omit
the linear term?
My only explanation for this is, that R somehow "detects" polynomial
expressions in model formulae and treats them specially.
Could anybody tell me a bit more on this subject?

Logistic Discrimination Analysis
...build a model with
m1<-glm(f~. , family=binomial(link="logit"),data=frame);
pv<-as.vector(predict(m1))
prob<-plogis(pv)
does then "prob" predict the probability of a sample to belong to group 1?
Is this equivalent to logistic discrimination analysis?
