Acknowledgments
We wish to acknowledge stimulating discussions with and advice from Christopher J. L. Murray in the development of our approach and analytic tools relating to the analysis and estimation of uncertainty in mortality and GBD estimates. We also acknowledge the assistance of staff of the former Global Program on Evidence for Health Policy at WHO, who helped substantially in the analysis of uncertainty, namely: Doris Ma Fat, Brodie Ferguson, Mie Inoue, and Niels Tomijima. Finally, we thank two referees for extremely useful comments and suggestions that have substantially improved this chapter.
