当然要想确证是否增产不是这么简单的事,不过我这里用的是洗心作为合作者的那篇文章的同样手法。

we conducted an analysis of covariance (ANCOVA) to test whether the yield differed significantly among years, location (Europe or the United States), percentage of GM used or any of the interactions. To identify the model with the best fit to the data, we used an Akaike's information criterion-based approach (Burnham and Anderson 1998, Anderson 2008) to compare all possible models including different combinations of independent variables and their interactions. The best fitting model included year, location and the interaction between year and location as independent effects.

要反驳那篇文章,或者判断一下它的质量啥的,都是可以的,但首先一定得看懂人家的文章。: S1 Y* p7 s4 ?
