CompareCICs: Inference on CICs.

In zrmacc/CICs: Inference on Cumulative Incidence Curves

Inference on CICs.

Description

Inference for the difference and ratio in summary statistics comparing two CICs.

Usage

CompareCICs(
  time,
  status,
  arm,
  strata = NULL,
  sum_stat = "AUC",
  param = NULL,
  reps = 2000,
  alpha = 0.05
)

Arguments

time	Observation time.
status	Event status. The event coded as 1 is assumed to be the event of interest.
arm	Arm, assumed to have two levels, coded 0/1.
strata	Optional stratification factor.
sum_stat	Summary statistic, from among 'AOC', 'AUC', 'Quantile', 'Rate'.
param	Truncation time, if ‘sum_stat' is ’AOC', 'AUC', or 'Rate'; quantile probability, if ‘sum_stat' is ’Quantile'.
reps	Bootstrap replicates.
alpha	Alpha level.

Value

Object of class compCICs containing:

• '@cis': Observed difference and ratio in areas with confidence intervals.

• '@cics': Cumulative incidence curves.

• '@pvals': Bootstrap and permutation p-values.

• '@reps': Bootstrap and permutation realizations of the test statistics.

• '@marg_stats': Marginal test statistics.

• '@stratum_stats': Stratum test statistics.
