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.
