Hello all,

I have used logit for multiple roc curves and am looking for how to put them all on the same graph.

logit death_30d scorenew if svar == 0
lroc if svar == 1

logit death_30d mfifive if svar == 0
lroc if svar == 1

logit death_30d asa_class if svar == 0
lroc if svar == 1

Does anyone know how to put all these graphs on the same plot?
