In order to study the dynamic changes in gas concentration, to reduce gas hazards, and to protect and improve mining safety, a new method is proposed to predict gas concentration. The method is based on the opposite degree algorithm. Priori and posteriori values, opposite degree computation,...

Forecasted mortality rates using mortality models proposed in the recent literature are sensitive to the sample size. In this paper we propose a method based on Bayesian learning to determine model-specific posterior distributions of the sample sizes. In particular, the sample size is included...

This paper proposes a multi-population approach to forecasting mortality rates for the less developed countries in a coherent way. The majority of these countries have witnessed faster mortality declines among the young and the working age population, whereas in developed countries, the...
