Obscuration diagnostics vs. intrinsic AGN luminosity, parameterized by . The lower limits on are displayed for illustrative purposes and not included in the survival analysis calculation. Survival analysis indicates a marginal statistically significant correlation among three of these relationships (ρ = 0.273, 0.185, 0.349, and −0.302, respectively), however, a wide scatter is evident. Color coding same as Figure  3.
