Abstract

ABSTRACT In contrast to point forecasting, interval forecasting provides the degree of variation associated with forecasts. Accurate forecasting can help governments formulate policies for tourism, but little attention has been paid to interval forecasting of tourism demand. This study contributes to apply neural networks to develop interval models for tourism demand forecasting. Since combined forecasts are likely to improve the accuracy of point forecasting, forecast combinations are used to construct the proposed models. Besides, grey prediction models without requiring that data follow any statistical assumption serve as constituent models. Empirical results show that the proposed models outperform other considered interval models.
