Description
Data originally analysed by Andersen et al (1993) on the survival of 205 patients in Denmark with malignant melanoma, and used by Claeskens and Hjort (2008) to illustrate focused model selection in Cox regression.
Usage
1
Format
A data frame with 205 rows and the following columns:
- ptno
Patient identification number
- death
Survival status: 1 = dead from illness, 2 = censored, 4 = dead from other causes
- days
Survival time in days
- depth
Invasion depth: factor with levels 1, 2, 3
- infilt
Infection infiltration level, a measure of resistance to the tumour: factor with levels 1 (high resistance), 2, 3, 4 (low resistance)
- epith
Indicator for epithelioid cells present
- ulcer
Indicator for ulceration
- thick
Thickness of the tumour in 1/100 mm
- sex
Sex. Factor with levels "female","male" and reference level "female"
- age
Age in years
- years
Survival time in years (instead of days)
- thick_centred
Version of thick centred around its mean and rescaled, defined as (thick - 292)/100.
