Abstract: Based on a group of variables obtained from actual hourly observations of visiting the website of football world cup 2018 during thirty days (the period of the competition), this paper suggested a statistical model to improve the performance quality of E-service-FIFA2018. The dependent variable was response time in seconds and the independent variables were type of connection machine (Smart phones, I-pad, I-phones, Tablets, Laptop, Desktop), duration of logging, distances between countries and the country of champion, classification of teams. Holt’s method (HM) and Holt-Winters’ method (HWM) were used. The results showed that the (HWM) method was the best method to improve the performance of quality of E-service and that performance was influenced by type of connection machine (Smart phones, I-pad, I-phones, Tablets, Laptop, Desktop). |
Keywords and phrases: time series analysis, smoothing techniques (HM, HWM), detectable and visible smoothing (α).
