AGN + TO AMIGA 79.3 ± 6.9 108.2 ± 7.1 5.9%
HCG 95.5 ± 7.2 100.9 ± 7.4 16.7%

SFN AMIGA 115.9 ± 7.1 98.1 ± 5.7 0.05%

Notes. The rows correspond to the distribution of galaxies (sample) and the columns to the probability of harbouring an AGN, an AGN + TO or a SFN. The numbers in italics are the cross-estimated, calculated using the presented method. The p-value is computed using a binomial test for a given probability and two different distributions.
