Japanese breast cancer data
Description
Function that organises US prostate data in apc.data.list
format.
The data set is taken from table 2 of Holford (1983), which contains age-specific counts of deaths and midperiod population measured in 1000s, during the period 1935-1969. Reported in 5 year age groups and 5 year period groups.
The original source was Cancer deaths: National Center for Health Statistics, 1937-1973 Population 1935-60: Grove and Hetzel, 1968 Population 1960-69: Bureau of the Census, 1974
The data set is in "AP"-format.
Usage
data.US.prostate.cancer()
Value
The value is a list in apc.data.list
format.
response |
matrix of cases |
dose |
matrix of cases/rates |
data.format |
logical equal to "AP". Data organised with age-groups in rows and period-groups in columns. |
age1 |
numeric equal to 50. This is the label for the first age group covering ages 25-29. |
per1 |
numeric equal to 1935. This is the label for the first period group covering period 1955-1959. |
coh1 |
NULL. Not needed when data.format="AP" |
unit |
numeric equal to 5. This is the width of the age and period groups. |
per.zero |
NULL. Not needed when data.format="AP" |
per.max |
NULL. Not needed when data.format="AP" |
time.adjust |
0. Thus age=50 in period=1935 corresponds to cohort=1935-50+0=1885, and indeed the centers of the age and period groups, that is age=52 and period=1937 translate into cohort=1937-52+0=1885. |
label |
character. "US prostate cancer". |
