In Orion-Corporation/barts: Bayesian Adaptive Rules for Treatment Selection

Simulate a study

Description

Simulate a study

Usage

simulate_study(study, theta, a, b, n_draws = 3000)

Arguments

study	A study whose phases will be simulated in sequence.
theta	A vector of true event probabilities in each arm.
a, b	Vectors of parameters to the beta prior with elements for each arm. Recycled to match the length of theta if possible.
n_draws	The number of draws to sample from the posterior for evaluating posterior probabilities in allocation rules.

study for options for study types. phase() for defining study phases. allocation_rule for available rules for treatment allocation.

Examples

# A single-phase study uses the same allocation rule throughout
simulate_study(
  single_phase_study(n = 240, rule = rule_1(epsilon = 0.1)),
  a = 1,
  b = 1,
  theta = 0.2 + 1:4 / 10
)

# A multi-phase study can e.g. have a burn-in period with another rule
simulate_study(
  multi_phase_study(phases = list(
    phase(n = 40, rule = randomization_list()),
    phase(n = 200, rule = rule_1(epsilon = 0.1))
  )),
  a = 1,
  b = 1,
  theta = 0.2 + 1:4 / 10
)
