alon_data {EMMIXgene}

Normalized gene expression values from Alon et al. (1999).

Description

A dataset containing centred and normalized values of the logged expression values of a subset of 2000 genes taken from Alon, Uri, et al. "Broad patterns of gene expression revealed by clustering analysis of tumor and normal colon tissues probed by oligonucleotide arrays." Proceedings of the National Academy of Sciences 96.12 (1999): 6745-6750. The method of subset selection was described in G. J. McLachlan, R. W. Bean, D. Peel; A mixture model-based approach to the clustering of microarray expression data , Bioinformatics, Volume 18, Issue 3, 1 March 2002, Pages 413–422.
