Solution Efficacy
There is naturally a question as to why these analytic attempts are not more successful in discriminating among the two classes. In most medical and probably most biological entities various attributes will be highly correlated. Figure 3 present the correlation matrix for data set #2. Here it can be seen that a high degree of correlation exists. In general this makes statistical regression less accurate or questionable at least. This limitation will certainly be present in all attempts at discrimination of biological entities until or unless orthogonal characteristics can be found
