Venn plot for sets of informative features identified in CNV-145 (left panel) and MA-145 (right panel) data sets. There is little overlap between informative features identified by three methods for CNV data. In particular, there is only one variable recognised as relevant by all three filtering methods. The agreement for the gene expression is much higher - for each method the number of variables that is common with at least one other method is larger than 68% of all variables identified as relevant by this method
