data.Italian.bladder.cancer: Italian bladder cancer data

In apc: Age-Period-Cohort Analysis

Description

Function that organises Italian bladder data in apc.data.list format.

The data set is taken from table IV of Clayton and Schifflers (1987a), which contains age-specific incidence rates (per 100,000 person-years observation) of bladder cancer in Italian males during the period 1955-1979. Numerators are also available. The original source was the WHO mortality database.

The data set is in "AP"-format.

Usage

data.Italian.bladder.cancer()

Value

The value is a list in apc.data.list format.

rates	matrix of mortality rates. This is not needed for the apc.data.list format, but included as this is the original data formats
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 25. This is the label for the first age group covering ages 25-29.
per1	numeric equal to 1955. 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=25 in period=1955 corresponds to cohort=1955-25+0=1930, and indeed the centers of the age and period groups, that is age=27 and period=1957 translate into cohort=1957-27+0=1930.
label	character. "Italian bladder cancer".
