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? M.
