It is also noted that the relative forecast accuracy enhancement diminishes for forecast lead-times beyond 20 time steps (hours).
They investigated the relative forecast accuracies of PI and RI as a function of time and found that their time variations were highly correlated with the occurrence of large earthquakes: RI outperformed PI during time intervals after 1960 within which M ≥ 6 earthquakes occurred.
Forecast errors were calculated by subtracting fitted values from actual health state values and dividing by the mean actual health state value to convert absolute forecast errors into relative forecast errors as a percentage of the actual sample mean health state value.

Figure 7 Relative forecasting performance of models with and without respective effects.
The use of different and inhomogeneous procedures leads to an inherent difficulty to judge what is the best performing model, or more generally, to evaluate relative forecasting performances.
It is true that the IFS analysis suggests that discretionary policy changes have "saved £17bn" compared to what would otherwise have happened, but that's different: that has been almost entirely offset by other changes, policy and non-policy driven, that have pushed up spending relative to forecast.
As for the stimulus, economies in countries that enacted relatively large programs, like the United States, China and Australia, have survived fairly well this year, relative to forecasts.
With growth still slowing, and inflation pressures either easing outright or disappointing relative to forecasts, I do not believe the conditions are in place to warrant a rise in the bank rate".
Each trades at a discount to its three-year price-to-sales average and to its respective industry on a price-to-earnings basis for the current fiscal year as well as on a price-to-earnings growth basis (measuring 2008 price-to-earnings relative to forecasts on long-term earnings growth).
Directly correcting the bias of forecasts using the relative change between forecast and control simulations has been shown to marginalize hydrologic uncertainty, reduce model bias, and remove systematic variance when predicting mean monthly and mean annual streamflow, prompting our investigation for maxima streamflow.
Additionally, the narrower widths of the 95% prediction intervals for our forecasting model relative to the forecasting model based only on census trends over time, suggest that more precise predictions can be obtained using our forecasting model.
