cusum_limit_sim {cusum}

Simulate control limit given false signal probability alpha for CUSUM charts

Description

Simulate control limit given false signal probability alpha for CUSUM charts

Usage

cusum_limit_sim(failure_probability, n_patients, odds_multiplier,
  n_simulation, alpha, seed = NULL)

Arguments

failure_probability

Double. Baseline failure probability

n_patients

Integer. Number of patients in monitoring period /sample size

odds_multiplier

Double. Odds multiplier of adverse event under the alternative hypothesis (<1 looks for decreases)

n_simulation

Integer. Number of simulation runs

alpha

Double. False signal probability of CUSUM

seed

Integer. Seed for RNG

Value

Returns the control limit for signalling performance change (double)

Examples

# simulate control limits for alpha = 0.05
cusum_limit_sim(
  failure_probability = 0.05,
  n_patients = 100,
  odds_multiplier = 2,
  n_simulation = 1000,
  alpha = 0.05,
  seed = 2046
