time_exposed_ins {qlifetable}

Data frame of time exposed at risk for a population of immigrants/portfolio entries

Description

Computes for each integer age and each combination of age and seasonal quarter the total time exposed at risk (in years) of a population of immigrants/new policies (new production) during the year of the event. The computation is performed using the associated data frame of quarterly variables corresponding to the population obtained using the quarterly_variables function.

Usage

time_exposed_ins(x)

Arguments

x

A data.frame output of the quarterly_variables function.

Value

A data frame with the time exposed at risk for each (potential) combination of integer age and age and season quarter of the input dataset. The data frame has the following components:

age

Integer age to which the time exposed at risk corresponds.

quarter.age

Age quarter to which the time exposed at risk corresponds.

quarter.calendar

Calendar (time, season) quarter to which the time exposed at risk corresponds.

time.exposed

Total time (in years) exposed at risk of the population during the quarter determined for the combination of 'age', 'quarter.age' and 'quarter.calendar'.

Note

The time exposed at risk is computed for each death from the beginning of the year in which the event occurred until the moment of occurrence of the event. Please see the note in the time_exposed_stock function.
