generate_data: Generate Data

In XuemeiDing/survival19: Deal with Stratified Cox Proportional Hazard Model

Description

The function generate_data generates example survival data

Usage

generate_data(true_beta = c(c(0.5, -0.5, 1, -1, 1.5), rep(0, 5)),
  F_pre = 1:10, gamma = rep(1, 10), mean_sample_size = 50,
  Sigma_z1 = diag(length(true_beta)), censoring_up_bound = 30,
  censoring_trunc = 3, order = T)

Arguments

true_beta	true parameters
F_pre	a unique list of facilities
gamma	true facility effects of each facility, notice length of gamma must be the same as length of F_pre
mean_sample_size	expected sample size of each facility (stratum), a scalar same in all facilities
Sigma_z1	Var-Cov matrix of design matrix
censoring_up_bound	maximum value that the censoring time can take
censoring_trunc	maximum observation time
order	whether the output data should be ordered by time

Value

a list of generated data:

delta	event indicator
z	design matrix
facility	which facility each patient belongs to
num_facility	number of facilities (strata)
time	obseved time for each patient
true_beta	true parameters
N	number of patients

Examples

surv_dat = generate_data()
