 note = {application/pdf, postprint, It is known that if a capacity is convex then the Dempster-Shafer update rule for the capacity is equivalent to the maximum likelihood update rule for the core of the capacity. This paper shows that the converse is also true; that is, a capacity must be convex if these two rules are equivalent.},
