| mortmod {LifeTables} | R Documentation |
Underlying model in the HMD life table system
Description
This function generates a complete (up to age 110+) human mortality rate profile given a certain family and level of mortality
Usage
mortmod(pattern, sex="female", alpha=0)
Arguments
pattern |
An integer from 1 to 7 indicating the underlying family pattern |
sex |
"male" or "female". Indicates the sex of the desired schedule |
alpha |
A scalar which determines the quantity to add or subtract from the underlying cluster pattern. Typical alpha values will not exceed an absolute value of 4, although it is possible to take on larger values. Defaults to 0. |
Details
The pattern argument identifies the shape or pattern of mortality and then alpha determines the level by weighting a set of age-specific deviations to add or subtract (depending on the sign of alpha) to the underlying cluster pattern.
Value
model.patt |
A vector of length 24 which contains a complete set of age-specific logged mortality rates for age intervals 0-1, 1-4, 5-9, 10-14, ..., 110+ |
