“…In this study, we have used the Box and Jenkins (1970) ARIMA and Box and Tiao (1975) ITSA methods to measure the effect of swine flu in Brunei. This is because the ITSA method is appropriate for explaining the dynamics and the impact of interruptions and changes of TS in a more detailed and accurate manner (Baldigara & Mamula, 2015;Park, Lee, & Song, 2016;Aboagye-Sarfo et al, 2016;Chang & Lin, 1997;Biglan, Ary, & Wagenaar, 2000;Ferrand, Kelton, Guo, Levy, & Yu, 2011;Chung et al, 2009;Wu & Hayashi, 2014). The ARIMA and ITSA methods can provide an appropriate measure of the impacts of crisis events, which advise practical actions to overcome problems associated with tourism, economic and other business matters.…”
