A nonparametric permutation-based methodology was used to determine whether the slope of the regression line of a country remained constant over time or whether so-called joinpoints, a core feature of the statistical software 笑在应用直线模型可以获得倾斜变化和更好的拟合的发生。超过90％的鲨鱼咬入事件发生在美国，澳大利亚，南非和新西兰海岸。由于其中三个海岸在转化为咬速时出现了负趋势，因此整体趋势正在减少。鲨鱼咬率下降的潜在原因 - 除了世界上人口的增加，导致更多的海滩，讨论了由于过度捕捞而导致的鲨鱼减少。SN - 2633-4666 UR - https://doi.org/10.1155/2019/7184634 Do - 10.1155 / 2019/7184634 JF - 海洋生物学PB - Hindwi Kw - ER -
