Apologies for cross posting, but both these groups are full of smart and helpful people ....
In a normal discriminant analysis, a very common graphical summary is an ROC curve, plotting 1-specificity against sensitivity. I am now working with a 3 way discriminant (that is, the dependent variable has 3 levels). I was wondering if anyone had come across any graphical summaries of such models.
TIA as always
