Global Estimation of Neonatal Mortality using a Bayesian Hierarchical Splines Regression Model Monica Alexander and Leontine Alkema The folder accompanying this paper contains: 1) A 'code' folder, which contains all the neccesary R code to produce estimates described in the paper. 2) A documentation PDF, which describes what required data and formats, and how to run the model using the supplied code. Code to produced more recent estimates is available from http://childmortality.org/. The input data is available from http://childmortality.org/. This includes both neonatal mortality rates and the underlying data for children under 5. The data used in 2015 estimation is available at http://childmortality.org/2015/.
