moths

<p>Macro-Lepidoptera captured in a light trap at Rothamsted Experimental Station during 1935.</p>

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.
