The term 'GeneSelector' refers to a filter selecting those
genes which are consistently identified as differentially
expressed using various statistical procedures. 'Selected'
genes are those present at the top of the list in various
ranking methods (currently 14). In addition, the stability of
the findings can be taken into account in the final ranking by
examining perturbed versions of the original data set, e.g. by
leaving samples, swapping class labels, generating bootstrap
replicates or adding noise. Given multiple ranked lists, one
can use aggregation methods in order to find a synthesis.
