quantile: Quantiles of the age-at-death distribution of a life table

In lifecontingencies: Financial and Actuarial Mathematics for Life Contingencies

Quantiles of the age-at-death distribution of a life table

Description

S4 method for the quantile generic: quantiles of the age at death implied by a lifetable, obtained by linear interpolation on the survivorship column l_x.

Usage

## S4 method for signature 'lifetable'
quantile(x, probs = seq(0, 1, 0.25), age = min(x@x), names = TRUE, ...)

Arguments

x	A lifetable or actuarialtable object.
...	Further arguments (currently unused).
probs	Numeric vector of probabilities in [0, 1].
age	Youngest age to condition on (default: the youngest tabulated age). Quantiles refer to the age at death given survival to age.
names	Logical: if TRUE (default) the result is named with the probabilities, as quantile does.

Value

A numeric vector of age-at-death quantiles.

quantile(soa08Act)
quantile(soa08Act, probs = c(0.1, 0.9), age = 65)
