Dear All, I would like to use R function 'selectFGR' of fine gray model in competing risks model. I used the 'Melanoma' data in 'riskRegression' package. Some of the variables are factor. I get solution for full model but not in variable selection model. Any advice how to use factor variable in 'selectFGR' function. The following R code is produced below for reproducibility. library(riskRegression) library(pec) dat <...

...ula (see code in link), I'm a bit confused how prediction is going to work. At the initial time t=0 I have no idea of the future particularly in which time group the new customer will be. To compare my models I use the time depended AUC calculated by the "score" function from package riskRegression. It internally uses a prediction function but when applying it to the extended model and the new test set it says "strata(time group) not found". When splitting my test set with survSplit the same way I did for the training set, it works and I get a nice AUC plot. But I am afraid if...

Which confint() method do you have in mind? There is at least four of them by default in R, and many additional classes could make use of stats:::confint.default by implementing vcov(). >
