%description
Fits unimodal and multimodal gambin distributions to species-abundance
distributions from ecological data, as in in Matthews et al. (2014)
<DOI:10.1111/ecog.00861>. 'gambin' is short for 'gamma-binomial'. The main
function is fit_abundances(), which estimates the 'alpha' parameter(s) of
the gambin distribution using maximum likelihood. Functions are also
provided to generate the gambin distribution and for calculating
likelihood statistics.
