Armstrong (2001) proposed ex ante conditions under which the gains in accuracy that result from combining are expected to be highest: (1) a number of evidence-based forecasts can be obtained; (2) the forecasts draw upon different methods and data; and (3) there is uncertainty about which forecast is most accurate. 3.1.The combination of improving demand together with limited supplies and low inventories in most markets has been driving ore and alloy prices higher in early 2021. Renewed Covid-19 restrictions in South Africa are again propelling both chrome and manganese prices higher this month. We are forecasting upward pricing momentum to continue in most ...

    The results shown in Table 6 for the Don River indicate that the best improvements for HS prediction accuracy are provided by the RUS-Bagging method: the CE HS is 0.585 (an increase from 0.511 of the individual learner), and the PI HS is 0.668 (an increase from 0.61 of the individual learner). While both these metrics show an improvement in HS ...As more weather forecasts begin to include probabilistic information, significant efforts will be required not only to effectively communicate this new information, but also to ensure that users understand the definition of the event being forecast.7 Examples of such efforts are the ongoing discourse between the NWS, emergency managers, and the ...

    Under which of the following conditions will a forecast combination be most likely to lead to an increases in forecast accuracy? If the different models have very different individual MAPEs Which of the following is true about the convention, used by some, in which all forecasts are equally weighted in a combination? Spatial coverage and timing: These can be considered together because forecasts may often trade off accuracy in space and time. Verifications of the temporal and spatial characteristics of convection will likely need to include a probabilistic tolerance for errors that increases as the forecast extends farther into the future.The forecast for the game could be further improved by waiting until the minute before the match ends, but again it is hard to see how anyone would accept this as a forecast. One could not want to compare the prediction accuracy of a person who forecasts games while in progress versus those that forecast the game before the game begins.

    Skill is the accuracy of the forecasts of interest relative to the accuracy of forecasts produced by a standard of reference such as climatology or persistence. The skill of an SI forecast is found for all 12 stations using MSE clim as the reference forecast where MSE clim is as given in the appendix. The subscript clim indicates climatology.Stock and Watson present a comprehensive collection of forecast combination schemes, which they subsume under the categories 'simple combination forecasts', 'discounted MSE forecasts', 'shrinkage forecasts', 'factor model forecasts', and 'time-varying-parameter (tvp) combination forecasts'.In our out-of-sample analysis, we consider only two types of time-t combination forecasts: (i) the mean ...Finally, we posit that analyst forecasts for firms whose analysts forecast under unfavorable conditions do not fully incorporate the information in financial statement-based forecasts after mandatory IFRS adoption.

The technique is applied to both simulated verification sets as well as weather data at eight stations in Utah, and a loss function based on dynamic time warping (DTW) is used.
