Description

Define prior functions used in PStrata.

Usage

prior_flat()

prior_normal(mu = 0, sigma = 1)

prior_t(mu = 0, sigma = 1, df = 1)

prior_cauchy(mu = 0, sigma = 1)

prior_lasso(mu = 0, sigma = 1)

prior_logistic(mu = 0, sigma = 1)

prior_chisq(df = 1)

prior_inv_chisq(df = 1)

prior_exponential(beta = 1)

prior_gamma(alpha = 1, beta = 1)

prior_inv_gamma(alpha = 1, beta = 1)

prior_weibull(alpha = 1, sigma = 1)

Arguments

mu, sigma, df, alpha, beta

parameters for the prior distribution

Value

A list, including the following items.

name: name of the distribution
type: type of the distribution, one character string of "real" or "positive"
args: a named list of all the input parameters
call: a function call object of the prior distribution on the parameters
