给定形状不同的两组界标数据，确定形状变化可以通过各个界标的扰动来解释的程度是有用的。我们提出了一种方法来评估这一点，基于分析的相对减少的形状之间的距离，可以通过改变一个单一的地标的位置。该方法适用于一组标志性的数据从颈椎的两个亚种的大猩猩。Copyright Biometrika Trust 2003，Oxford University Press.
Given two sets of landmark data which differ in shape, it is useful to determine the extent to which shape variation can be explained by the perturbations of individual landmarks. We propose a method for assessing this, based on analysing the relative reduction in distance between the shapes that can be achieved by varying the location of a single landmark. This method is applied to a set of landmark data from the cervical vertebrae of two subspecies of gorillas. Copyright Biometrika Trust 2003, Oxford University Press.
