“…Statistical models have been used at subcountry and country scales (Estes et al, 2013;Hernandez-Barrera et al, 2016;Wang et al, 2014;Zhou and Wang, 2015) in addition to continental (Iglesias et al, 2012) and global simulations (Lobell and Burke, 2010). They have also been used to for analysis of the role of different drivers controlling yield variability and trend of various crops including maize (Estes et al, 2013;Iglesias et al, 2012;Lobell and Burke, 2010;Zhou and Wang, 2015), rice (Wang et al, 2016;Zhou and Wang, 2015) and wheat (Estes et al, 2013;Hernandez-Barrera et al, 2016). Further detailed reviews of the use of statistical models include Boote et al (2013); Shi et al (2013); White et al (2011).…”
