For the colon cancer data set, the human desmin gene had a relatively high frequency (57% versus the next four highest of 32%, 28%, 28% and 26% when training sample contained half the data and 97% versus the next highest of 52%, 50%, 49%, and 45% when the training sample contained four-fifths of the data). This evidence concerns the gene DES and malignant colon neoplasm.
