Laplacian principle of indifference
Principle of indifference
In the context of expert combination, having no evidence related to expert forecasting performance, models should weight experts equally. (Bol, 2017)
Brunswik lens model A framework for relating a set of criteria (or indicators), expert’s judgment, and the ”correct” judgment. (Fra, 2011; Sei, 2013)
