Evidential Intervals

In general, when a body of evidence is interpreted by Gister-CL relative to a propositional statement of interest, the result is an evidential interval. An evidential interval is a subinterval of [0, 100]%. The lower bound, called the support or belief, indicates the degree to which the evidence supports the propositional statement in question, while the upper bound, called the plausibility, indicates the degree to which the evidence fails to refute the proposition, i.e., the degree to which it remains plausible. This evidential interval typically corresponds to bounds on a probability. Thus, the lower and upper bounds are often called the lower and upper probabilities, respectively. Examples of how these intervals are interpreted follow: Evidential Intervals
