BetaConversion: Converting beta distribution parameters

In SRenan/XCIR: XCI-inference

Description

Convert parameter values between different beta distribution parametrization

Usage

betaParam(
  alpha = NULL,
  beta = NULL,
  m = NULL,
  theta = NULL,
  mu = NULL,
  sigma2 = NULL
)

Arguments

alpha	A numeric. First shape parameter
beta	A numeric. Second shape parameter
m	A numeric. Mode
theta	A numeric. Concentration
mu	A numeric. Mean
sigma2	A numeric. Variance

Details

This function needs two parameters that caracterise the beta distribution (alpha and beta, mode and concentration or mean and variance) and returns all parametrizations.

Value

A named numeric with all equivalent formulations of the distribution.

Examples

betaParam(alpha = 5, beta = 5)
betaParam(m = 0.5, theta = 10)
betaParam(mu = 0.5, sigma2 = 0.02272727)
