Claim One:
1. A method of identifying a set of informative genes whose expression correlates with a chemosensitive class or a chemoresistant class across samples which are determined to be either sensitive or resistant to a compound by growth inhibition, wherein more than one compound is assessed, comprising the steps of: a) sorting genes by degree to which their expression in said sample which is determined to be either sensitive or resistant to a compound by growth inhibition correlates with the chemosensitive class or the chemoresistant class; b) determining whether said correlation is stronger than expected by chance; and c) repeating steps a) and b) for each compound being assessed; wherein a gene whose expression correlates with either the chemosensitive class or chemoresistant class more strongly than expected by chance is an informative gene, thereby identifying a set of informative genes.
