c_parametrizations {bmm}

Convert between parametrizations of the c parameter of the SDM distribution

Description

Convert between parametrizations of the c parameter of the SDM distribution

Usage

c_sqrtexp2bessel(c, kappa)

c_bessel2sqrtexp(c, kappa)

Arguments

c

Vector of memory strength values

kappa

Vector of precision values

Details

c_bessel2sqrtexp converts the memory strength parameter (c) from the bessel parametrization to the sqrtexp parametrization, c_sqrtexp2bessel converts from the sqrtexp parametrization to the bessel parametrization.

See the online article for details on the parameterization. The sqrtexp parametrization is the default in the bmm package.

Value

A numeric vector of the same length as c and kappa.

Examples

c_bessel <- c_sqrtexp2bessel(c = 4, kappa = 3)
c_sqrtexp <- c_bessel2sqrtexp(c = c_bessel, kappa = 3)
