format_data_ourmethod: Format observed data for TM (Tayob and Murray method)

In umich-biostatistics/corrsurv: Two-Sample Tests for Correlated Survival Endpoints

Description

Formats the data for the method described in Tayob, Murray 2015. This function is for internal use by TM().

Usage

format_data_ourmethod(X, delta, Z, t)

Arguments

X	vector containing observed time to terminating event
delta	vector that is 1 if terminating event is observed and 0 if patient is censored
Z	array of times to recurrent events. Number of columns corresponds to maximum number of recurrent events observed for a patient
t	vector containing start times of follow-up windows chosen

Value

a list containing

• ID - vector containing numeric identifying numbers for each patient corresponding to row numbers of input data

• X_tk - vector containing observed time to combined end-point for each follow-up window

• delta_tk - vector containing combined end-point event indicator. 1 if combined-endpoint is observed and 0 if censored

• t_k - vector containing start times of corresponding follow-up window

• n - number of patients in dataset
