Description

Data example for analyzing the primary response in ODS design (zhou et al. 2002)

Usage

ods_data

Format

A matrix with 400 rows and 5 columns. The first 200 observations are from the simple random sample, while 2 supplemental samples each with size 100 are taken from one standard deviation above the mean and below the mean, i.e. (Y1 < 0.162) and (Y1 > 2.59).

Y1

primary outcome for which the ODS sampling scheme is based on

X

expensive exposure

Z1

a simulated covariate

Z2

a simulated covariate

Z3

a simulated covariate
