mortalityTable.period-class {MortalityTables}

Class mortalityTable.period - Period life tables

Description

A period life table, giving death probabilities for each age, up to maximum age omega. The baseYear slot can be used to hold information about the period.

Slots

ages

The ages corresponding to the entries of the deathProbs

deathProbs

The one-year death probabilities for the ages

exposures

(Optional) exposured used to determine death probabilities (can be used as weights for smoothing, for variances, etc.)

Examples

linTable = mortalityTable.period(name="linear mortality", ages = 0:50, deathProbs = 0:50/50)
constTable = mortalityTable.period(name="const. mortality", ages = 0:50,
                                   deathProbs = c(rep(0.1, 50), 1))
plot(linTable, constTable, title="Comparison of linear and constand death probabilities")

# A sample observation table with exposures and raw probabilities
obsTable = mortalityTable.period(
    name = "trivial observed table",
    ages = 0:15,
    deathProbs = c(
