Prostate cancer data of American men from a subset of SEER Data
SUMMARY:
DATA DESCRIPTION:
ARGUMENTS:
- region
-
patients from seven geographical regions
- record
-
record id within each region
- group
-
distinct age groups over the seven regions
- period
-
three periods correspond to patients who are diagnosed
in [1973,1985], [1973,1997] or [1985,1997].
- age
-
ten recodes of patient's age at diagnosis. Each recode refers to a 5-year
age group from 40, 45 up to 90.
- counts.unc
-
number of uncensored patients in a period and a category of region and age group
- age.unc
-
average age of uncensored patients in a period and a category of region and age group
- time.unc
-
average survival time (months) of uncensored patients in a period and a category of region and age group
- counts.cen
-
number of censored patients in a period and a category of region and age group
- age.cen
-
average age of censored patients in a period and a category of region and age group
- time.cen
-
average censoring time (months) of censored patients in a period and a category of region and age group

age * as.factor(period) + age^2 * as.factor(period), cluster = cbind(region, record),
family = binomial, link = "logit", variance = "glm.scale", correlation = "independent",
