The influence of the frequency of directional change on the physiological responses to intermittent exercise in elite football players.
Despite the common occurrence of directional change in football, few studies have attempted to investigate the demands of players performing such movement patterns (Stevens et al., 2014; Akenhead et al., 2014; Dellal et al., 2010). The aim of the current thesis was to identify the physiological …

Error magnitude and directional accuracy for time series forecasting evaluation
… measured in terms of error magnitude. However, directional accuracy is as important as error magnitude especially in economics since it considers directional movement of the data. This research attempted to combine the two types of measurements by introducing a new element, the slope value. This …
