“…For the shorter term (one to three quarters ahead) the TVP-STSM, CSM, TVP model and BSM, all of which belong to the family of state space models, take the top four positions in the forecasting competition according to the MAPE. The very good short-term forecasting performances of the TVP model, CSM and BSM are in line with the findings of past tourism forecasting studies, such as those of Song and Witt (2000), González and Moral (1995) and Turner and Witt (2001). In particular, the TVP-STSM, CSM and TVP model, all of which incorporate explanatory variables into the model specifications, generate the most accurate one-and two-quarters-ahead forecasts.…”
