AREDS

Description

Real dataset of bivariate interval and right censored data with 628 subjects and three covariates. The dataset is a reshaped version of the AREDS data from the CopulaCenR package. The dataset was selected from the Age-related Eye Disease Study (AREDS) (AREDS Group, 1999). The two events are the progression times (in years) to late-AMD in the left and right eyes.

Usage

data(areds)

Format

war is a 628 row data frame with the following columns

t11, t12

left and right bounds of the intervals for the left eye. If t12 = NA then the observation is right-censored.

t21, t22

left and right bounds of the intervals for the right eye. If t22 = NA then the observation is right-censored.

SevScore1, SevScore2

baseline AMD severity scores for left and right eyes, respectively. Possible values are: 4, 5, 6, 7, 8.

age

age at baseline.

rs2284665

a genetic variant covariate highly associated with late-AMD progression. Possible values are: 0, 1, 2.

cens1, cens2

type of censoring for left and right eyes.

cens

joint censoring indicator for left and right eyes.
