Box-uniform (independent uniform) prior

Box-uniform (independent uniform) prior

Usage

prior_uniform(low, high)

Arguments

low

Numeric vector of lower bounds (one per parameter). Naming the vector (e.g. c(beta = 0, gamma = 0)) attaches those names to every downstream parameter matrix, posterior sample, and diagnostic plot. NA/NaN are rejected; -Inf is accepted (matching high's Inf) but makes the prior improper, so sample_prior() on it errors unless it is first bounded with prior_truncated().

high

Numeric vector of upper bounds (one per parameter). Same finiteness rule as low, with Inf in place of -Inf.

Value

An nsbi_prior object.

Examples

prior <- prior_uniform(low = c(-2, -2, -2), high = c(2, 2, 2))
theta <- sample_prior(prior, 5)
