%description
A suite of tools to mitigate sampling bias in species occurrence records
by thinning data in the environmental space (E-space). This process can
improve the accuracy and precision of species distribution models (SDM,
also known as ecological niche models, ENM). The package offers a
data-driven protocol to determine thinning parameters using kernel-density
bandwidth selection. Two thinning methods are provided (stochastic and
deterministic) to reduce over-sampled environmental conditions and
down-weight outlier observations. The name 'bean' reflects the core
principle of the method: each 'pod' (a grid cell in E-space) is allowed to
contain only a limited number of 'beans' (occurrence points). See
Silverman (1986, ISBN:978-0-412-24620-3) and Rousseeuw and Leroy (2003,
ISBN:978-0-471-48855-2) for the underlying statistical methods.
