I have to differentiate two diseases based on the genetic features. These two diseases are labelled as class '0' and class '1' in the database. Interestingly, all the patients with the class 0 will get the class 1. On other words, if a patient has disease of class 0, surely have diseases class 1. The research question is : How many patients with class 1 will get class 0?
Do you think binary classifications and performance measurement such as AUC can help in this problem?
