tfr: Compute total fertility rate from fertility rates

Description

Compute total fertility rates from age-specific fertility rates contained in a demogdata object.

Usage

tfr(data, PI=FALSE, nsim=500, ...)

Arguments

data
Demogdata object of type "fertility" such as obtained from read.demogdata, forecast.fdm
PI
If TRUE, produce a prediction interval.
nsim
Number of simulations to use when computing a prediction interval.
...
Other arguments passed to simulate when producing prediction intervals.

Value

  • If data are of class demogdata, the function returns a time series of fertility rates. If data are from forecast.fdm, the function returns an object of class forecast containing point forecasts and (optionally) prediction intervals.
