Coherent updating on finite spaces
Enrique Miranda.
We compare the different notions of
conditional coherence within the behavioural
theory of imprecise probabilities
when all the spaces are finite.
We show that the differences between
the notions are due to conditioning
on sets of (lower, and in some
cases upper) probability zero. Next,
we characterise the range of coherent
extensions, proving that the greatest
coherent extensions can always
be calculated using the notion of regular
extension.
