WebCalibration means that forecasts and average realized frequencies are close. We develop the concept of forecast hedging, which consists of choosing the forecasts so as to guarantee that the expected track record can only improve. This yields all the calibration results by the same simple basic argument while differentiating between them by the … WebCalibration means that for each forecast x the average of the realized actions in the periods in which the forecast was x is, in the long run, close to x. Calibration can …

The calibration error, defined as ∑ p mp − p np , quantifies the extent to which the forecaster deviates from being well-calibrated. mary jo hightower tucsonWebCalibration means that forecasts and average realized frequencies are close.
