Thanks for your answer! You helped me a lot! Is there any documentation of the DMVQ procedure. I couldn't find any. Unfortunately I have to write my master thesis about all this. Kind of hard without formulas and sufficient documentation by SAS 😄 Maybe you can answer me one more question about the CCC. The greater the better... I know. But what if it is just monoton increasing, so the more cluster, the greater it is. Seems kind of nonsense to me or quite unreliable. Are other statistics more important like the R² or cluster distance? Thank you! 🙂

Hey Noel, ROC curves help you to assess models for a binary target (sensitivity and 1-specificity connect the dots of true positives and false negatives). Clustering is unsupervised learning, which means you don't need a target. This is why you don't see ROC curves if you don't have a target that can be assessed in terms of sensitivity and 1-specificity. I hope it helps, M
