model selection, stepAIC(), and coxph() (fwd)
Hello,
My question concerns model selection, stepAIC(), add1(), and coxph().
In Venables and Ripley (3rd Ed) pp389-390 there is an example of using
stepAIC() for the automated selection of a coxph model for VA lung cancer
data.
A statistics question: Can partial likelihoods be interpreted in the same
manner as likelihoods with respect to information based criterion and
likelihood ratio tests?
