Description

Create demogdata object suitable for plotting using plot.demogdata and fitting an LC or BMS model using lca or an FDA model using fdm.

Usage

demogdata(data, pop, ages, years, type, label, name, lambda)

Value

year

Vector of years

age

Vector of ages

rate

A list containing one or more rate matrices with one age group per row and one column per year.

label

label

lambda

Arguments

data

Matrix of data: either mortality rates or fertility rates

pop

Matrix of population values of same dimension as data. These are population numbers as at 30 June of each year (i.e., the "exposures"). So, for example, the number of deaths is data*pop if data contains mortality rates.

ages

Vector of ages corresponding to rows of data.

years

Vector of years corresponding to columns of data.

type

Character string showing type of demographic series: either “mortality”, “fertility” or “migration”.

label

Character string of the name of area from which the data are taken.

name

Name of series: usually male, female or total.

lambda

Box-Cox transformation parameter.
