Description

Convenience function to create a simple uniform prior distribution

Usage

createUniformPrior(lower, upper, best = NULL)

Arguments

lower

vector of lower prior range for all parameters

upper

vector of upper prior range for all parameters

best

vector with "best" values for all parameters

Examples

# NOT RUN {
set.seed(1)

prior <- createUniformPrior(lower = c(0,0), upper = c(0.4,5))

# c(2, 3) outside of limits
prior$density(c(2, 3))
# -Inf

# c(0.2, 2) within limits
prior$density(c(0.2, 2))
# -0.6931472


# sample from prior
prior$sampler()
# [1] 0.2291413 4.5410389


## the prior object can be passed to createBayesianSetup()

# log-likelihood density function (needed for createBayesianSetup)
ll <- function(x) sum(dnorm(x, log = TRUE))

setup <- createBayesianSetup(prior = prior, likelihood = ll)
# }
