gen_data {coxrobust}

Generate Data from the Proportional Hazards Regression Model

Description

Generates data set from the proportional hazards regression model without or with contamination.

Usage

gen_data(n, beta, cont = 0, p.censor = 0)

Arguments

n

number of observations.

beta

vector of regression coefficients.

cont

fraction of contaminated observations.

p.censor

probability of censoring.

Value

Data frame containing the following variables:

• timevector of survival times.

• statusvector of censoring status.

• X1, X2, ...explanatory variables (their number is determined by the dimension of vector of regression coefficients).

Examples

if (interactive()) {
gen_data(50, c(2,-2), cont = 0.05)
}
