“…Capture–Recapture (CR) methods are statistical techniques widely employed to estimate the size of an elusive population for which it is impossible to get a complete enumeration. This task, applied initially to ecology for the study of fish and wildlife populations (Matechou & Argiento, 2023; Otis et al., 1978; Wu & Holan, 2017), is now common to many other application fields such as epidemiology (Böhning et al., 2020; Chao et al., 2001; Maruotti et al., 2023) and social sciences (Böhning et al., 2018; Böhning & van der Heijden, 2009; Brittain & Böhning, 2009; Di Cecco et al., 2020; Farcomeni, 2022; Silverman, 2020).
