Av. {DetLifeInsurance}

Varying Life Insurance: Arithmetic Progression

Description

Calculates the present value of a varying life insurance according to a arithmetic progression.

Usage

Av.(
  x,
  h,
  n,
  k = 1,
  r = 1,
  i = 0.04,
  data,
  prop = 1,
  assumption = "none",
  variation = "none",
  cap = 1
)

Arguments

x

An integer. The age of the insuree.

h

An integer. The deferral period.

n

An integer. Number of years of coverage.

k

An integer. Fractions per year.

r

The variation rate. A numeric type value.

i

The interest rate. A numeric type value.

data

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

prop

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

assumption

A character string. The assumption used for fractional ages ("UDD" for uniform distribution of deaths, "constant" for constant force of mortality and "none" if there is no fractional coverage).

variation

A character string. "inter" if the variation it's interannual or "intra" if it's intra-annual.

cap

A numeric type value. Amount insured for the first year/period.

Value

Returns a numeric value (actuarial present value).

Note

For an increasing life insurance coverage, 'r' must be 1.
