The aggregation of the variables that compose an indicator, as GDP, which should be forecasted, is not mentioned explicitly in literature as a source of forecasts uncertainty. In this study based on data on U.S. GDP and its components in 1995-2010, we found that GDP one-step-ahead forecasts made...

The aggregation of the variables that compose an indicator, as GDP, which should beforecasted, is not mentioned explicitly in literature as a source of forecasts uncertainty. In thisarticle we demonstrate that variables aggregation is an important source of uncertainty inforecasting and we...

The aggregates, like GDP, can be forecasted using two different strategies, the criterion of predictions’ accuracy being used to select the best strategy. The aim of this paper is to find out what is the best strategy to be used in predicting GDP in Romania. In this study, for data series of...
