V_AD. function

Reserve Valuation for Decreasing Life Insurance

Reserve Valuation for Decreasing Life Insurance

Calculates the reserve for the decreasing life insurance up to the moment t.

V_AD.( px, x, h, n, k = 1, cantprem = 1, premperyear = 1, i = 0.04, data, prop = 1, assumption = "none", variation = "none", cap, t )

Arguments

  • px: A numeric value. The value of the premium paid in each period.
  • 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. Number of fractions per year.
  • cantprem: An integer. The total number of premiums.
  • premperyear: An integer. The number of premiums to be paid 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.
  • prop: A numeric value. It represents the proportion of the mortality table 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 inter-annual or "intra" if it's intra-annual.
  • cap: A numeric type value. Amount insured for the first year/period.
  • t: An integer. The moment of valuation (in months if it is a fractional coverage or in years if it is not).

Returns

A data frame with Premium, Risk, 1/E and reserve values up to the moment t.
