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")
