Example of possible running sum statistics. The figure shows all possible running sum statistics for an ordered list of 8 genes of which 4 belong to a functional category. The red labeled running sum statistic has a RSC value of 12 and the corresponding p-value is . The numbers on the x-axis refer to the index and the number of possible running sum values in the current step.
