In Jiahui1902/APCI: A New Age-Period-Cohort Model for Describing and Investigating Inter-Cohort Differences and Life Course Dynamics

Construct a cohort index matrix for any number of age and period groups

Description

This function returns a cohort index matrix for any number of age and period groups. The cohort index matrix will then be used to extract age-period interaction effects contained in each cohort.

Usage

ageperiod_group(age_range, period_range,
age_interval, period_interval,
age_group = NULL, period_group = NULL)

Arguments

age_range, period_range

Numeric vector indicating the actual age and period range (e.g., 10 to 59 years old from 2000 to 2019).

age_interval, period_interval, age_group, period_group

Numeric values or character vectors indicating how age and period are grouped. age_interval and period_interval are numbers indicating the width of age and period groups respectively. age_group and period_group are character vectors explicitly listing all potential age and period groups. Either age_interval(period_interval) or age_group (period_group) have to be defined when unequal_interval is TRUE.

Value

It returns a matrix respresenting the relationship among age, period, and cohort groups under the current setting.

Examples

## age and period groups have equal width
ageperiod_group(age_range = 10:59, period_range = 2000:2019,
                age_interval = 5, period_interval = 5)
ageperiod_group(age_range = 10:59, period_range = 2000:2019,
                age_group = c("10-14","15-19","20-24","25-29",
                              "30-34","35-39","40-44","45-49",
                              "50-54","55-59"),
                period_group = c("2000-2004","2005-2009","2010-2014","2015-2019"))

## age and period groups have unequal width
ageperiod_group(age_range = 10:59, period_range = 2000:2019,
                age_interval = 10, period_interval = 5)
ageperiod_group(age_range = 10:59, period_range = 2000:2019,
                age_group = c("10-19","20-29","30-39","40-49","50-59"),
                period_group = c("2000-2004","2005-2009","2010-2014","2015-2019"))
