Exponential Prior for Scale Parameters

Specifies an Exponential(rate) prior for positive scale parameters. This is a convenience function equivalent to gamma_prior(shape = 1, rate = rate).

Usage

exponential_prior(rate = 1)

Arguments

rate

Positive numeric. Rate parameter of the Exponential distribution. Default: 1.

Value

An object of class "bgms_scale_prior" with family = "exponential".

Examples

exponential_prior()
#> Scale prior: Exponential(rate = 1)
exponential_prior(rate = 2)
#> Scale prior: Exponential(rate = 2)
