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.
