sample.prior: Sample from prior distributions of calibrated parameters

In DARTH-git/darthpack: The Decision Analysis in R for Technologies in Health (DARTH) coding framework

Sample from prior distributions of calibrated parameters

Description

sample.prior generates a sample of parameter sets from their prior distribution.

Usage

sample.prior(n_samp, v_param_names = c("p_S1S2", "hr_S1", "hr_S2"),
  v_lb = c(p_S1S2 = 0.01, hr_S1 = 1, hr_S2 = 5), v_ub = c(p_S1S2 = 0.5,
  hr_S1 = 4.5, hr_S2 = 15))

Arguments

n_samp	Number of samples.
v_param_names	Vector with parameter names.
v_lb	Vector with upper bounds for each parameter.
v_ub	Vector with lower bounds for each parameter.

Value

A matrix with 3 rows and n_samp rows. Each row corresponds to a parameter set sampled from their prior distributions

Examples

v_param_names  <- c("p_S1S2", "hr_S1", "hr_S2")
n_param        <- length(v_param_names)
v_lb <- c(p_S1S2 = 0.01, hr_S1 = 1.0, hr_S2 = 5)  # lower bound
v_ub <- c(p_S1S2 = 0.50, hr_S1 = 4.5, hr_S2 = 15) # upper bound
sample.prior(2)
