New methods for combining forecasts are introduced. The combined forecast for the next period is made using different forecasts weighted according to variable weights, based on the differences between each forecast and the actual value of the forecasted variable during the previous periods. The methods are implemented on actual data sets and are found to be very stable and accurate.
