Methods of selecting a portfolio of markers for use in a diagnostic applications include defining diagnostic parameters, establishing a relationship among the parameters so that they are optimized, and selecting an optimal group of markers for the diagnostic application. The diagnostic parameters can include a measure of the relative degree of expression of a gene, a measure of the variation in the measurement of the degree of expression of the gene, and the relationship between the diagnostic and discriminating parameters can be a mean variance relationship. n Machines programmed to conduct the method and articles that comprise instructions for their operation are further aspects of the invention. |
