Specify a prior with uniformly distributed marginals

A specialisation of create_prior() where the parameter space is described by independent uniform marginals.

Usage

create_uniform_prior(
  lower = 0,
  upper = 1,
  names = "Uniform",
  .n_dim = NULL,
  .name_repair = c("unique", "universal", "check_unique")
)

Arguments

lower, upper

Numeric vector of bounds for the uniform distribution.

names

An optional character vector. Names for the variables in the prior distribution.

.n_dim

An optional positive integer. The number of dimensions of the prior distribution.

.name_repair

An optional, case-sensitive string. How to repair names. Options are "unique" (default), "universal", or "check_unique". See vctrs::vec_as_names() for details.

Value

A uniform_prior, a subclass of ernest_prior with an efficient implementation of the unit hypercube transformation.

Note

See vctrs::vector_recycling_rules for additional information on how parameters are recycled to a common length.

Examples

prior <- create_uniform_prior(lower = c(3, -2), upper = c(5, 4))
#> New names:
#> • `Uniform` -> `Uniform...1`
#> • `Uniform` -> `Uniform...2`
prior$fn(c(0.33, 0.67))
#> [1] 3.66 2.02
