We develop a Bayesian multivariate analysis of expert judgment elicited using an extended form of pair-wise comparisons. The method can be used to estimate the effect of multiple factors on the probability of an event and can be applied in risk analysis and other decision problems. The analysis provides variance predictions of the quantity of interest that incorporate dependencies amongst the v...

We consider subjective versions, competing ones and those that change dynamically over time. These are illustrated by exampl...
