Fractional_table function

Fractional table of mortality

Creates a fractional mortality table for a given mortality table.

Fractional_table(data, frac, i = 0.04, assumption = "UDD")

Arguments

• data: A data.frame of the annual mortality table, with the first column being the age and the second one the probability of death.
• frac: An integer. The number of fractions per year.
• i: A numeric type value. The interest rate.
• assumption: A character string. The assumption used for fractional ages ("UDD" for uniform distribution of deaths and "constant" for constant force of mortality).

Returns

Returns a data.frame object containing fractional age and death probability vectors.

Examples

Fractional_table(CSO80MANB,2,0.04,"constant")
Fractional_table(CSO80MANB,2,0.04,"UDD")
