Various functions developed at the Department of Biostatistics, Epidemiology, Biostatistics and Prevention Institute, University of Zurich. Currently implemented topics:

  • several CI’s for proportions,
  • several CI’s for diagnostic tests,
  • Fagan-Nomogram,
  • bootstrap CI’s for the kappa coefficient,
  • intraclass-correlation coefficients including CI’s,
  • agreement for continuous measurements (Bland-Altman plot),
  • CI for the area under the curve (AUC),
  • Mantel-Haenszel estimator,
  • Mantel-Cox hazard ratio estimator,
  • CI for the Kaplan-Meier estimate at given time points,
  • CI for quantile of a Kaplan-Meier or cumulative incidence estimate,
  • sample size computations for two-sample Mann-Whitney test, McNemar test, binary diagnostic test (via normal approximation and simulation),
  • natural re-parametrization of Weibull output from survreg,
  • hazard ratio and event time ratio interpretations,
  • a plot to check the adequacy of the Weibull model.
