amt (version 0.2.2.0)

distributions: Functions create statistical distributions

Description

make_distributions creates a distribution suitable for using it with integrated step selection functions

Usage

make_distribution(name, params, vcov = NULL, ...)
make_exp_distr(rate = 1)
make_hnorm_distr(sd = 1)
make_lnorm_distr(meanlog = 0, sdlog = 1)
make_unif_distr(min = -pi, max = pi)
make_vonmises_distr(kappa = 1, vcov = NULL)
make_gamma_distr(shape = 1, scale = 1, vcov = NULL)

Value

A list of class amt_distr that contains the name (name) and parameters (params) of a distribution.

Arguments
