Worm et al. (Research Articles, 3 November 2006, p. 787) used a power relation to predict a global collapse of fisheries by the year 2048. However, a linear regression of the data for the past 40 years yields an excellent fit, with a predicted date of collapse of 2114. Thus, long-term projections of fisheries collapse are highly dependent on the specific statistical model used.
沃姆等人(《研究论文》,2006年11月3日,第787页)运用幂函数关系预测到2048年全球渔业将崩溃。然而,对过去40年的数据进行线性回归得出的拟合度极佳,预测的崩溃时间为2114年。因此,渔业崩溃的长期预测高度依赖所使用的特定统计模型。
