Receiver operating curve after firthlogit command

[Edsel Ing]

After I perform penalized maximum likelihood logistic regression with firthlogit, what is the easiest way to get the ROC for the model?

(lroc command will not work)

firthlogit response c.predictor
predict double xb, xb
roctab response xb

Thank you much!
