In this paper, we consider coherent imprecise probability assessments on ยฎnite families of conditional events and we study the problem of their extension. With this aim, we adopt a generalized deยฎnition of coherence, called g-coherence, which is based on a suitable generalization of the coherence pr

โฆ Synopsis
This paper presents the historical and philosophical definition of subjective probabilities (also called degree of belief or Bayesian probabilities). It presents a case for the scientist to use subjective probabilities in the process of parameter estimation and evidence evaluation under the Bayesian framework. It is emphasised that Bayesian methodology does not pretend to get the 'true' probabilities: it is an effective method to analyse, criticise, check the 'coherence' of people's opinions, and to help them in revising their opinions in a 'coherent' way.
