Abstract

() M2 where M1 and M2 are the total numbers of cells for map 1 and map 2, respectively, and m1 and m2 are the numbers of occupied cells of the respective maps. Critically, this empirical approach has been shown in practice to work well, or at least substantially better than existing alternatives, for estimating the abundances of
