摘要Some techniques of probability forecasting are applied to time-series data on interest rates, money stock, consumer prices, and output. A sequential method for debiasing (recalibrating) predictive distributions based on previously issued distributions and outcomes is developed, and our estimated sequences of unadjusted and recalibrated distributions are tested for calibration. After recalibration, the calibration hypothesis cannot be rejected for most of the time-series and forecast horizons. Furthermore, traditional point forecasts can be improved when the forecast are derived from recalibrated distributions.
