versicolor from the other to classes and I got approx. 70% of accuracy
testing on train set. In iris, versicolor stands "between" the 2 other so
one can expect lda not to perform well since it cannot cluser the negative
instances (seposa+virginica) together (Is this correct?) (KNN=96% in xval.)
Now, I use my "real" dataset (900 instances, 21 attributes), which 2 classes
can be serparated with accuracy no more than 80% (10xval) with KNN, SVM, C4.5
and the like.
So I was very surprised to see that lda also gets an accurac...
