Hello, I am trying to use BIC instead of AIC in the logistic regression model selection. I change "k" parameter in step() and stepAIC() functions to log(N) to achieve that, but it seems to have no effect - I get exactly the same models as with the AIC (k=2, default). Is this a currently unimplemented feature? Thanks, Alex. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
