cusum_alpha_sim: Simulate false signal probability alpha given control limit...

In cusum: Cumulative Sum (CUSUM) Charts for Monitoring of Hospital Performance

Description

Simulate false signal probability alpha given control limit for CUSUM charts

Usage

cusum_alpha_sim(failure_probability, n_patients, odds_multiplier,
  n_simulation, limit, 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
limit	Double. Control limit for signalling performance change
seed	Integer. Seed for RNG

Value

Returns False signal probability of specified CUSUM chart.

Examples

#
# control limit can be obtained with cusum_limit_sim(),
# here it is set to an arbitrary value (2.96)

# simulate false positive probability of CUSUM
cusum_alpha_sim(
  failure_probability = 0.05,
  n_patients = 100,
  odds_multiplier = 2,
  n_simulation = 10000,
  limit = 2.96,
  seed = 2046
)
