This package fits the gambin distribution to
species-abundance distributions from ecological data. ‘gambin’ is short
for ‘gamma-binomial’. The main functions are
fit_abundances, which estimates the alpha
parameter of the gambin distribution using maximum likelihood, and
mult_abundances which estimates alpha for
multiple sites / samples after standardising for the number of
individuals. Recent functions are also provided to generate the gambin
distribution and for calculating likelihood statistics. The package now
provides functionality to fit multimodal gambin distributions.
The package is currently on CRAN and can be installed via
install.packages("gambin")Alternatively, you can install the developmental version via
devtools::install_github("txm676/gambin")
