qfrac {DetLifeInsurance}

Fractional Probability of Death

Description

Calculates the fractional probability for a person of x+s/k dies before age x+(s+1)/k.

Usage

qfrac(x, s, k, i, data, assumption, prop)

Arguments

x

An integer. The age of the insuree.

s

An integer. Fraction of the year.

k

An integer. Number of fractions per year.

i

The interest rate. A numeric type value.

data

A data.frame containing the mortality table, with the first column being the age and the second one, the probability of death.

assumption

A character string. The assumption used for fractional ages ("UDD" for uniform distribution of deaths and "constant" for constant force of mortality).

prop

A numeric value. It represents the proportion of the mortality table being used (between 0 and 1).

Value

The fractional probability of death.
