The Leukemia Survival Data
Description
A dataset on the survival of acute myeloid leukemia in 1,043 pateietns, first analyzed by Henderson et al. (2002). It is of interest to investigate possible spatial variation in survival after accounting for known subject-specific prognostic factors, which include age, sex, white blood cell count (wbc) at diagnosis, and the Townsend score (tpi) for which higher values indicates less affluent areas. Both exact residential locations of all patients and their administrative districts (24 districts that make up the whole region) are available.
Format
A data frame with 1043 rows and 9 variables:
time: survival time in days
cens: right censoring status 0=censored, 1=dead
xcoord: coordinates in x-axis of residence
ycoord: coordinates in y-axis of residence
age: age in years
sex:male=1 female=0
wbc:white blood cell count at diagnosis, truncated at 500
tpi: the Townsend score for which higher values indicates less affluent areas
district:administrative district of residence
