u5mr
u5mr is a open-source R package for estimating the child
mortality. Current implementation includes the Trussell version of the
Brass method using the Coale-Demeny model life tables and supporting
datasets of coefficients and automatic interpolating values between
probabilities of dying at a certain age and model tables.
To download the developmental version of the u5mr package, use the code below.
# install.packages("devtools")
devtools::install_github("myominnoo/u5mr")The first example is using Bangladesh survey data and model South of the Coale-Demeny life table.
library(u5mr)
## Using Bangladesh survey data to estimate child mortality
data("bangladesh")
bang_both <- u5mr_trussell(bangladesh, sex = "both", model = "south", svy_year = 1974.3)
