Effective Scoring Rules for Probabilistic Forecasts

Published: 01 April 1983 Publication History

Abstract

This paper studies the use of a scoring rule for the elicitation of forecasts in the form of probability distributions and for the subsequent evaluation of such forecasts. Given a metric distance function on a space of probability distributions, a scoring rule is said to be effective if the forecaster's expected score is a strictly decreasing function of the distance between the elicited and "true" distributions. Two simple, well-known rules the spherical and the quadratic are shown to be effective with respect to suitable metrics. Examples and a practical application in Foreign Exchange rate forecasting are also provided.
