prior: Specify a prior

In BayesianPlayground/bayesplay: The Bayes Factor Playground

Description

Specify a prior

Usage

prior(distribution, ...)

Arguments

distribution	the prior distribution (see details)
...	see details

Details

Available distributions

The following distributions can be used for the prior

• normal a normal distribution

• uniform a uniform distribution

• point a point The parameters that need to be specified will be dependent on the distribution

normal distribution

When distribution is set to normal then the following parameters must be set

• mean mean of the normal prior

• sd standard deviation of the normal prior

• range (optional) a vector specifying a paramter range

uniform distribution

When distribution is set to uniform then the following parameters must be set

• min the lower bound

• max the upper bound

point

When distribution is set to point then the following parameters may be set

• point the location of the point prior (default: 0)

Value

an object of class prior

Examples

# specify a half-normal (range 0 to Infinity) prior
prior(distribution = "normal", mean = 0, sd = 13.3, range = c(0, Inf))

# specify a normal prior
prior(distribution = "normal", mean = 0, sd = 13.3)

# specify a uniform prior
prior(distribution = "uniform", min = 0, max = 20)

# specify a point prior
prior(distribution = "point", point = 0)
