The Diabetic Retinopathy Data
Description
The data was colleceted to test a laser treatment for delaying
blindness in patients with dibetic retinopathy. The subset of 197
patiens given in Huster et al. (1989) is used.
Format
This data frame contains the following columns:
- id
a numeric vector. Patient code.
- agedx
a numeric vector. Age of patient at diagnosis.
- time
a numeric vector. Survival time: time to blindness or
censoring.
- status
-
a numeric vector code. Survival status. 1: blindness, 0: censored.
- trteye
a numeric vector code. Random eye selected for
treatment. 1: left eye 2: right eye.
- treat
a numeric vector. 1: treatment 0: untreated.
- adult
a numeric vector code. 1: younger than 20, 2: older than 20.
