GM(1,1) models have been widely used in various fields due to their high performance in time series prediction. However, some hypotheses of the existing GM(1, 1) model family may reduce their prediction performance in some cases. To solve this problem, this paper proposes a self-adaptive GM(1, 1) model, termed as SAGM(1, 1) model, which aims to sol...

while NGBM(1,1) model has been successfully used in various fields,there are still some limitations in NGBM(1,1) model: First, the existing NGBM(1,1) model family is all based on the assumption that some adjustable parameters are known, which reduced the prediction performance of the NGBM(1,1) model family. Then, the leap error from the differentia...

Purpose Accurate foreign tourist arrivals forecasting can help public and private sectors to formulate scientific tourism planning and improve the allocation efficiency of tourism resources. This paper aims to address the problem of low prediction accuracy of Chinese inbound tourism demand caused by the lack of valid historical data. Design/method...
