The Combination of Forecasts Using Rank-Based Techniques (engl.) (Quantitative Ökonomie)
3 Angebote vergleichen

The combination of forecasts is getting more and more important since it is easier to obtain multiple forecasts for the same event with the advance of computing. There is also increasing competition between forecasters leading to a variety of forecasts, e.g. Meteo Consult and Deutscher Wetterdienst for weather forecasts in Germany. The typical situation is the following: A decision maker, say a politician, a company executive, or a farmer is presented with the dilemma: There are several forecasts for the same event say the GDP growth rate, sales of a certain item, or the daily temperature. These are just examples for many more cases where we are confronted with this situation. Here, the combination of forecasts sets in. Even if the decision maker says: model x was best in the past, lets stick with forecast x he is already using a simple but justified com¬bining technique. He may also say: well, lets average those forecasts (to be on the safe side). This is an even simpler combining method since it does not consider any information on the prior performance of the forecaster or fore¬cast models, respectively. This book is going to present new non-parametric forecast combining methods based on ranks of past forecast errors. These techniques are com¬pared to existing combining methods by using an extensive data analysis, simulations, and a selection procedure. The main goal is to find out when or why a combining technique is best to come up with an universal algorithm, in this case the selection process.
