DETERMINATION OF WEIGHTING FACTORS IN COMBINING FORECASTS
Abstract
Combining forecasts has already proven to be a simple and practical method for improving the quality of forecasting. The use of all available information from various prediction methods makes it possible to increase the accuracy of forecasting even when individual methods are not accurate enough.
This article is a continuation of previously published reviews of different approaches and methods for constructing weighting factors to combine forecasts. In the last several decades, in the foreign literature a lot of studies have been published on comparative analysis and establishing various methods of combining forecasts. Unfortunately, Russian authors pay little attention to this trend in improving forecasting methodology, e.g. they do not compare various methods of combining forecasts. Those studies that do make such comparisons are limited only to a few simple methods. Many methods of combining forecasts that are widely used abroad are disregarded by the Russian scientists. This paper along with the previous reviews have been tasked with examining different approaches to obtaining weighting factors in combining forecasts, and introducing them to Russian scientists and researchers.
As a result, this article adds to the previously proposed classification (Voprosy statistiki, 2015, № 8) of basic and most frequently used methods of combining forecasts with a description of the obtained results and indicating scientific publications authored by both Russian and foreign researchers on the issue in question, with those studies that were excluded from the authors’ previous reviews.
