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 payments 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 interannual or "intra" if it's intra-annual.

cap

A numeric type value. The annualized value of the first payment.

t

An integer. The moment of valuation (in months if it is a fractional coverage or in years if it is not).

Value

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