womack: For internal use Womack prior

Description

Womack probability mass function with 'K' predictors and parameter 'rho'.

Usage

womack(K, rho)

Value

Given that all models of the same hierarchy has the same prior probability, this function returns one value for each hierarchy. including the null model (size=0)

Arguments

K

Number of predictors. It must be a positive integer.

rho

Value for the "rho" parameter. It must be positive real number

Examples

#Fixing rho=1 and 3 predictors
womack(K=3, rho=1)
#it returns Womack prior for all models of size 0 (the null model), 1,2 and 3 (the full model)
