N: number of time points; G: number of probe sets; N_C: number of significant genes picked up by C-statistic; N_G: number of significant genes picked up by G-statistic; N_K: number of significant periodic genes picked up by the intersection set K; N_D: number of significant other periodic genes or other patterned genes picked-up by the difference set D.
