Synthetic population data

Description

This is made-up time-to-event data with properties that make it useful for testing and demonstrating svycoxme functions. There is a single level of clustering, identified with group_id, and the X covariates depend on Z covariates.

Usage

pop

Format

A data frame with 20,000 rows and 10 columns:

X1

Observation-level N(\mu_{X1}, 1) distributed covariate where \mu_{X1}=0.5*(Z1 + 1)

X2

Cluster-level N(\mu_{X2}, 1) distributed covariate where \mu_{X2}=0.5*(Z2 + Z3)

X3

Cluster-level binary covariate where Pr(X3=1) = Z3

Z1

Stratum membership. Takes the values 1 to 5

Z2

cluster-level N(0,1) distributed covariate

Z3

cluster-level Uniform(0,1) distributed covariate

stat_time

Event or Censoring time

stat

Event/Censoring indicator. Event=1; Censoring=0

group_id

Unique cluster ID

obs_id

Unique observation ID

sampled

Sampling indicator. Is this observation in samp_srcs?
