From a mathematical point of view, combined forecasting could indeed promote forecasting accuracy (Wu 2007); while practically due to the uncertainty of every model's forecasting result, combing the forecasts is no doubt a superposition of all the uncertainties, leading to discrepancies with the actual production in oil and gas fields, thus indicating a limitation therein.
Climatological forecasts may indeed change the climate; there would be no point publishing papers about the effects of greenhouse gases otherwise.Also, no model, however sophisticated, can feed back into the forecast because true predictions about socio-natural systems often degenerate into undecidable propositions when they enter the public domain.
Gamson says fuel energy price forecasts can indeed be uncertain.
The sky, still pale, was cloudy, and the forecast did indeed call for rain.
Forecasting is indeed risky, because of factors like construction productivity, inflation, and the growth and bursting of speculative bubbles in both home prices and long-term interest rates.
The scale and pace of this consolidation is the big political judgment call of this budget, since even if such vast spending cuts are achievable politically there is a risk that growth will not return at the rates forecast, and indeed international growth will falter.
Leeb himself is forecasting higher, indeed skyrocketing, prices.
Precise and consistent production forecasting is indeed an important step for the management and planning of petroleum reservoirs.
The results on test set show the correction considering inherent errors of numerical techniques can integrate the physical with statistical information effectively and enhance the forecast accuracy indeed.
Indeed, economic forecasts are so important that the U.S. government generates forty-five themsand of theachach year.
But had they listened to the sage counsel of Nate Silver, their ESPN colleague who wrote a best-seller about how to distinguish true statistical signals from distracting background noise when making forecasts, they could indeed have avoided sending the basketball commentariat on a wild goose chase.
