In zrmacc/MCC: Functions for Comparing Mean Cumulative Count Curves

Calculate Mean Cumulative Function

Description

Tabulates the mean cumulative function. See equation 2.1 of <doi:10.1111/j.0006-341X.2000.00554.x>.

Usage

CalcMCF(idx, status, time, calc_var = TRUE, weights = NULL)

Arguments

idx	Unique subject index.
status	Status, coded as 0 for censoring, 1 for event, 2 for death.
time	Observation time.
calc_var	Calculate variance of the MCF?
weights	Jump weights.

Value

Data.frame with these columns:

• 'times', distinct observation times.

• 'censor', number of censorings.

• 'death', number of deaths.

• 'event', number of events.

• 'haz', instantaneous hazard (of death).

• 'surv', survival probability.

• 'event_rate', instantaneous event rate.

• 'mcf', mean cumulative function.

• 'se_mcf', standard error of the MCF.
