...> xx<-cuminc(ftime,fstatus,group) > plot(xx,lty=1,color=1:6) I end up with the 6 curves plotted on the same graph. Is there a way that I can plot a selection of these curves? (say only curves for cause 1, group=0 and cause 1 group=1).

Dear all, The variable selection in regression is usually determined by the training data using AIC or F value, such as stepAIC. Is there some R package that can consider both the training and test dataset? For example, I have two separate training data and test data. Firstly, a regression model is obtained by using training data, and then this model is tested by using test data. This process

...'t in the bootstrap sample (this would be repeated B times)...we chose the 0.632+ bootstrap estimator. There are many types of estimators for prediction error curves. How should we decide which is 'best'?

This is apparently a previously reported bug and perhaps fixed in some platform other than Windows (rw2001).Some
