dataPA: Date generation function

Description

Generate interval-censored data under generalized odds-rate model, with different combinations of right-censoring rate and cumulative baseline hazard function.

Usage

dataPA(N, case, alpha)

Arguments

N

size of dataset

case

data generation configuration; takes value in 1, 2 and 3.

alpha

parameter of link function; alpha=0 for the PH model and alpha=1 for the PO model.

Value

d1

vector indicating whether an observation is left-censored (1) or not (0).

d2

vector indicating whether an observation is interval-censored (1) or not (0).

d3

vector indicating whether an observation is right-censored (1) or not (0).

Li

the left endpoint of the observed interval; if an observation is left-censored, its corresponding entry should be 0.

Ri

the right endpoint of the observed interval; if an observation is right-censored, its corresponding entry should be Inf.

Z

design matrix of predictor variables (in columns); should be specified without an intercept term.

Details

The above function generate interval-censored data from generalized odds-rate model, under different simulation configurations. For further details please see Lu et al. (2019+).
