All three functions estimate life expectancy from lifetable.
The function flife.expectancy is primarily designed for forecast life expectancies and will optionally
produce prediction intervals. Where appropriate, it will package the results as a forecast object
which makes it much easier to product nice plots of forecast life expectancies.
The e0 function is a shorthand wrapper for flife.expectancy with age=0.
Usage
life.expectancy(
data,
series = names(data$rate)[1],
years = data$year,
type = c("period", "cohort"),
age = min(data$age),
max.age = min(100, max(data$age))
)
flife.expectancy(
data,
series = NULL,
years = data$year,
type = c("period", "cohort"),
age,
max.age = NULL,
PI = FALSE,
nsim = 500,
...
)
e0(
data,
series = NULL,
years = data$year,
type = c("period", "cohort"),
max.age = NULL,
PI = FALSE,
nsim = 500,
...
)Arguments
- data
Demogdata object of type “mortality” such as obtained from
read.demogdata, or an object of classfmforecastsuch as the output fromforecast.fdmorforecast.lca, or an object of classfmforecast2such as the output fromforecast.fdmpr.- series
Name of mortality series to use. Default is the first demogdata series in data.
- years
Vector indicating which years to use.
- type
Either
periodorcohort.- age
Age at which life expectancy is to be calculated.
- max.age
Maximum age for life table calculation.
- PI
If TRUE, produce a prediction interval.
- nsim
Number of simulations to use when computing a prediction interval.
- ...
Other arguments passed to
simulatewhen producing prediction intervals.
Value
Time series of life expectancies (one per year), or a forecast object of life expectancies (one per year).
Examples

france.LC <- lca(fr.mort,adjust="e0",years=1950:1997)
france.fcast <- forecast(france.LC,jumpchoice="actual")
france.e0.f <- life.expectancy(france.fcast)
france.fdm <- fdm(extract.years(fr.mort,years=1950:2006))
france.fcast <- forecast(france.fdm)
if (FALSE) {
e0.fcast <- e0(france.fcast,PI=TRUE,nsim=200)
plot(e0.fcast)}
