mortmod: 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 5 indicating the family which determines the underlying 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 3. Defaults to 0.
Value
model.pattA 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+
Details
The pattern argument identifies the shape or pattern of mortality and then alpha determins the quantity to add or subtract (depending on the sign of alpha) to the underlying cluster pattern.
