datagen: Date generation function

In PenIC: Semiparametric Regression Analysis of Interval-Censored Data using Penalized Splines

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.

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+).

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.
