The LifeInsureR Package For Traditional Life Insurance with Guarantee and Profit Participation

R package implementing general life insurance contracts

This package R6 classes to model traditional life insurance contracts like annuities, whole life insurances or endowments. All relevant quantities like premium decomposition, reserves and benefits over the whole contract period are calculated and potentially exported to 'Excel'. Mortalities are given using the 'MortalityTables' package.

Functions in LifeInsureR (1.0.1)

CalculationSingleEnum-class

Enum to define how much of a contract needs to be calculated automatically.

InsuranceContract.ParametersFill

Initialize the insurance contract parameters from passed arguments

PVfactory (R6Class for present values with arbitrary dimensions)

InsuranceContract.ParameterStructure

Full insurance contract parameter structure.

InsuranceContract.ParametersFallback

Use fallback values for missing contract parameters

PaymentTimeSingleEnum-class

Enum to describe when a benefit or premium payment is due (in advance or in arrears)

InsuranceContract

Base Class for Insurance Contracts

Base class for traditional Insurance Tarifs (with fixed guarantee, profit sharing and no unit-linked component)

InsuranceContract.Values

Data structure (filled only with NULL) for insurance contract class member values.

InsuranceContract.ParameterDefaults

Default parameters for the InsuranceContract class.

ProfitParticipationFunctions

Helper functions for profit participation

Convert the multi-dimensional costs array to a data.frame for output to a file

SexSingleEnum-class

Enum to describe possible sexes in an insurance contract or tariff.

Helper object to define rounding rules for the InsuranceContract, InsuranceTarif and ProfitParticipation classes.

Create a grid of InsuranceContract objects or premiums with each axis representing one varying parameter

TariffTypeSingleEnum-class

An enum specifying the main characteristics of the tarif.

ProfitComponentsMultipleEnum-class

Enum to define the different components of profit participation.

age.exactRounded

Calculate the age of the insured based on exact age at contract closing, rounded to the nearest birthday.

If hook is a function, apply it to val, otherwise return val unchanged

age.yearDifference

Calculate the age of the insured based on the difference of the bith year and contract closing year.

ProfitParticipation

Base Class for Profit Participation Schemes

exportInsuranceContract.xlsx

Export an insurance contract (object of class InsuranceContract) to an 'Excel' file

isRegularPremiumContract

Determine whether a contract (given all parameters) is a contract with regular premiums

initializeCosts

Initialize or modify a data structure for the definition of InsuranceTarif costs

costs.baseAlpha

Helper function to define base costs with base alpha, but otherwise unchanged costs

premiumRefundPeriod.default

Default premium refund period: for deferred contracts the deferral period, otherwise the whole contract

Calculate the rolling mean of length 2

costs.scaleAlpha

Helper function to modify alpha costs of an insurance contract individually

Replace missing values in ields by default fallback values

Replace all NA entries of a vector with the previous non-NA value

Overwrite all existing fields with default values given

filterProfitRates

Filter the whole data.frame of profit rates for the given profit classes

Pad the vector v to length l by repeating the last entry of the vector.

vmGlgExample.generateTest

Generate testthat output for unit-testing a tarif implementation

Pad a vector with 0 to a desired length

costsDisplayTable

Helper function to display all cost definitions in a concise table

valueOrFunction

If val is a function, evaluate it, otherwise return val

testVmGlgExample

Perform unit tests of given standard values of the insurance contract example

exportInsuranceContractExample

Export the example calculations of an insurance contract

Set all entries of the given vector to 0 up until index 'start'

Defines a frequency charge (surcharge for monthly/quarterly/semiannual) premium payments

isSinglePremiumContract

Determine whether a contract (given all parameters) is a single-premium contract or with regular premiums

makeContractGridDimname

Create human-readable labels for the dimensions in a contractGrid()

deathBenefit.linearDecreasing

Describes the death benefit of a linearly decreasing whole life insurance (after a possible deferall period)

Update one component of an InsuranceTarif's cost structure

deathBenefit.annuityDecreasing

Describes the death benefit of a decreasing whole life insurance (after a possible deferall period)
