A Bayesian Approach to Developing a Stochastic Mortality Model for China

Abstract: Summary Stochastic mortality models have a wide range of applications. They are particularly important for analysing Chinese mortality, which is subject to rapid and uncertain changes. However, owing to data‐related problems, stochastic modelling of Chinese mortality has not been given adequate attention. We attempt to use a Bayesian approach to model the evolution of Chinese mortality over time, taking into account all of the problems associated with the data set. We build on the Gaussian state space formulat… Show more

“…First, the MI rates projected by these factor-based models are likely to be jagged across ages and/or cohorts, due to the non-smooth factor estimates. To overcome this problem, studies, such as Renshaw and Haberman [ 39 ], Delwarde et al [ 10 ], Currie [ 7 ], Pitt et al [ 36 ] and Li et al [ 33 ], have considered using penalization methods or splines to smooth the age-specific factors. Nevertheless, such smoothing methods can hardly be applied simultaneously to both age- and period-specific factors to achieve a smooth two-dimensional MI surface.…”

“…Especially, for countries with poor mortality data quality, the problem is more remarkable. In view of the large fluctuation of population mortality data in China sampling survey years and the lack of mortality data in some years, Siu et al [13] use the Gaussian condition space model to fill and correct the data under the Bayesian framework. However, this method is only for a single population and does not consider the relationship between populations [13].…”

“…Despite these benefits, the use of Bayesian methods in mortality modelling is still sparse and has been largely confined to DFM models (Czado et al, 2005;Pedroza, 2006;Reichmuth and Sarferaz, 2008;Cairns et al, 2011;Antonio et al, 2015;Li et al, 2015;van Berkum et al, 2017;Alexopoulos et al, 2019;Li et al, 2019;Wang et al, 2021). 3 To our knowledge, the only paper employing BVAR to mortality data is Njenga and Sherris (2020).…”
