A statistical approach is adopted to determine the origin of the FIR continuum in AGN. (IRAS) and optical properties of Markarian Seyferts are submitted to a comparative analysis together with those of starburst galaxies, here assumed to exemplify purely thermal emission. Distributions and various correlations are analyzed using survival analysis techniques to exploit the information in the censored data. This study shows no significant differences in IR continuum properties between Seyfert 1s and Seyfert 2s. For a given galactic mass, both Seyfert types show an excess in mid-IR and FIR emission relative to starbursts. 50 refs.
