Heligman-Pollard parameter conversion to age-specifc probabilites of death.

Description

Converts a set of Heligman-Pollard mortality model parameters into age-specific probabilities of death.

Usage

hp.nqx(HPout, age, M = "total")

Arguments

HPout	A model object created with HP.mod with the Heligman-Pollard estimated params.
age	A vector containing the ages at which the probability of death will be calculated.
M	The type of probabilities to be calculated. Can be both "natural" mortality, "total" mortality and mortality due to an external risk.

Value

Set of age specific probabilities of death equal to the length of age.

Note

Utility function called by HP.CI.
