cusum_alpha_sim {cusum} | R Documentation |
Simulate false signal probability alpha given control limit for CUSUM charts
cusum_alpha_sim(failure_probability, n_patients, odds_multiplier, n_simulation, limit, seed = NULL)
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 |
Returns False signal probability of specified CUSUM chart.
# # 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 )
