The paper develops and applies an expert-based stochastic population forecasting method, which can also be used to obtain a probabilistic version of scenario-based official forecasts. The full probability distribution of population forecasts is specified by starting from expert opinions on the future development of demographic components. Expert opinions are elicited as conditional on the reali...

The soft expert models are richer than soft set models since the soft set models are created with the help of one expert whereas but the soft expert models are made with the opinions of all experts. In the present paper, we introduce soft expert generalized closed sets (soft expert g-closed sets) and soft expert generalized open sets (soft expert g-open sets) in soft expert topological spaces a...

Sewer degradation is mainly a stochastic process. The future condition of sewers can be predicted with models based on condition states. In The Netherlands, the ‘SPIRIT’ model is being developed which combines expert opinion and visual inspections to predict sewer degradation. The statistical method implemented in this model is based on Bayesian statistics. The likelihood function of condition ...

Expert witnesses use various methods to render dispassionate opinions. Some forensic psychiatrists acknowledge bias up front; other experts use principles endorsed by the American Academy of Psychiatry and the Law or other professional organizations. This article introduces CHESS, a systematic method for reducing bias in expert opinions. The CHESS method involves identifying a Claim or prelimin...
