Medians and Kolmogorov-Smirnov two sample tests for the statistical comparison of various distributions of the two Seyfert subtypes.

Distribution Median D p value

log 43.15 43.30 0.3 0.79
log 44.47 44.63 0.3 0.79
log 44.64 45.01 0.2 0.99

log λX –2.06 –1.70 0.2 0.98
log λ [OIII]  –1.76 –1.38 0.3 0.75

Notes. Kolmogorov-Smirnov two sample test examines the hypothesis that two samples comes from same distribution. D = Sup x |S1(x) – S2(x)| is the maximum difference between the cumulative distributions of two samples S1(x) and S2(x), respectively.
