However I intend to build the classifier without using the tests and just using the biopsy/other measures to determine the class label, to avoid circularity | |

| Mar 26, 2012 at 18:04 | comment | added | Jim Bo | Sorry if it was unclear! I thought the fact I could see a couple of clusters in the data might be helpful in the choise of model/classifier/rule | |
| Mar 26, 2012 at 17:49 | comment | added | Jim Bo | Not necessarily from all features.. it would also be great if we could find a sub-set that is as good as using all 15. | |
| Mar 26, 2012 at 17:46 | comment | added | Jim Bo | Exactly. I did the clustering to look for "structure" in the data, i.e. if I could see difference in patterns of scores between dis vs. non-disease. However my aim is to devise a (ideally simple and intuitive) scoring rule | |
| Mar 26, 2012 at 17:43 | comment | added | chl | It seems you want to use some kind of a supervised algorithm (where class membership is known in advance) as opposed to unsupervised methods (like clustering). Can you confirm that what you are after is simply devising a 'scoring rule' (Prob(individual i has disease)) from all 15 features? | |
