In HIV.LifeTables: HIV calibrated model life tables for countries with generalized HIV epidemics

Description

This function produces a complete set of mortality rates for ages 0, 1-4, 5-9, 10-14, ...,100+ and life table given a region, sex, and set of inputs which must include HIV prevalence and one of the following mortality indicators: life expectancy at birth (e0), child mortality alone (5q0), or child mortality with adult mortality (45q15)

Usage

hiv.mortmod(prev=NULL, e0=NULL, child.mort = NULL, adult.mort = NULL, model = 1, 
region = 1, sex = 1, lt = FALSE, nax=NULL, opt=TRUE)

Arguments

prev	HIV prevalence expressed as a percentage
e0	Life expectancy at birth (used only if model=1)
child.mort	Probability of death between age 0 and 5, 5q0 (used only if model=2 or model=3)
adult.mort	Probability of death between age 15 and 60, 45q15 (used only if model=3)
model	An interger to indicate which inputs will be used on the model. 1 for life expectancy, 2 for child mortality alone, 3 for child mortality with adult mortality
region	An integer to indicate which regional model to use. 1 for Africa, 0 for Caribbean or Latin American
sex	An interger to indicate the sex of the desired life table. 1 for female, 0 for male
lt	Logical. If TRUE a life table is calculated based on the estimated mortality rates. The user can supply nax values. Otherwise, the assumption of half the length of the age interval is used for nax values.
nax	If lt=TRUE, the user can supply a set of nax values
opt	If model=1, opt=TRUE will use a value for the weight for the first SVD component that produces a set of age-specific mortality rates that produce a life exepctancy at birth that matches the input life exepctancy.

Value

nmx	The estimated nmx values produced by the model
lt	If lt=TRUE A life table with age intervals matching those of the nmx schedule on which the table is built and with columns for age, nax, nmx, nqx, npx, ndx, lx, nLx, Tx, and ex.
lt.5q0	If lt=TRUE The probability of death between birth and age 5
lt.45q15	If lt=TRUE The probability of death between age 15 and 60

Note

If lt=TRUE, it is possible that the life table contains fewer age groups than the 22 in the estimated mortality rates if the mortality rates are high enough to kill off all people before the final age group, 100+.

## a set of mortality rates at 2.5 percent prevalence, life expectancy of 53, 
## for Caribbean Males
hiv.mortmod(prev=2.5, e0=53, model=1, region=0, sex=0, lt=FALSE)
