“…Although the applications of some nonlinear methods have gained remarkable success (Xiong et al, 2013;Yu et al, 2008;Yu et al, 2014;Zhang et al, 2015), the linear predictive regression is still the most popular in forecasting oil prices. The predictors incorporated in the predictive regressions include oil futures prices (Alquist and Kilian, 2010;Coppola, 2008;Moshiri and Foroutan, 2006), oil production (Baumeister and Kilian, 2012, 2014a, 2014b, oil inventory (Baumeister and Kilian, 2012;Ye et al, 2005Ye et al, , 2006, crack spread (Baumeister et al, Forthcoming;Murat and Tokat, 2009) and some high-frequency financial variables (Baumeister et al, 2015b).…”
