bcusum_arl_sim

Double. Control Chart limit for detecting deterioration/improvement.

Data Frame. First column are Parsonnet Score values within a range of <code>0</code> to
<code>100</code> representing the preoperative patient risk. The second column are binary (<code>0/1</code>)
 outcome values of each operation.

Double. Odds ratio of death under the null hypotheses.

Double. Odds ratio of death under the alternative hypotheses.

Compute ARLs of the Bernoulli CUSUM control charts using simulation.

Contains functions to set up risk-adjusted quality control charts in health care. For the variable life adjusted display (VLAD) proposed by Lovegrove et al. (1997) <doi:10.1016/S0140-6736(97)06507-0> signaling rules derived in Wittenberg et al. (2018) <doi:10.1002/sim.7647> are implemented. Additionally, for the risk-adjusted cumulative sum chart based on log-likelihood ratio statistic introduced by Steiner et al. (2000) <doi:10.1093/biostatistics/1.4.441> average run length and control limits can be computed with fast and accurate Markov chain approximations developed in Knoth et al. (2019) <doi:10.1002/sim.8104>.
