time_exposed_ins {qlifetable} | R Documentation |
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 |
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.
