BetaConversion: Converting beta distribution parameters

In 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 list 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)
