mod: Heligman-Pollard parameter coversion to age-specific probabilites of death.

Description

Calculates the age-specific probabilities of death using the Heligman-Pollard model.

Usage

mod(theta, x)

Arguments

theta

A vector containing values for the 9 parameters of the adapted Heligman-Pollard model.

x

A vector containing the ages at which to calculate the probabilities of death.

Value

A vector of probabilities of death at ages defined by x.
