笔记----------Notes----------
Austin Hughes' data: a point pattern of displaced amacrine cells in the retina of a rabbit. 152 “on” cells and 142 “off” cells in a rectangular sampling frame.
奥斯汀休斯的数据:一个点的模式流离失所的无长突单元在视网膜上的兔子。 152“上的”单元和142的“关闭”的单元,在一个矩形的采样帧。
The true dimensions of the rectangle are 1060 by 662 microns. The coordinates here are scaled to a rectangle of height 1 and width 1060/662 = 1.601 so the unit of measurement is approximately 662 microns.
真实尺寸的矩形是1060由662微米。这里的坐标被调整为矩形的高度和宽度1060/662 = 1.601“这样的度量单位是约662微米。
The data were analysed by Diggle (1986).
