Abstract:
In 2015, Statistics New Zealand released mortality estimates based on fully Bayesian statistical methods. As far as we know, this is the first time that a government statistical agency anywhere in the world has published official statistics based on 100% Bayesian methods. Statistics New Zealand is currently expanding the use of Bayesian methods to other outputs. There has been substantial international interest in this work. In the talk, we will argue that Bayesian methods are particularly appropriate for the type of estimation problems that government statistical agencies now face. We will give some examples of the methods we have developed for demographic estimation and forecasting. We will also look at some of the particular challenges that arise when using complex statistical methods for government statistics.
