笔记----------Notes----------
These data record the (x,y) locations and ages of bramble canes in a field 9 metres square, rescaled to the unit square. The canes were classified according to age as either newly emergent, one or two years old. These are encoded as marks 0, 1 and 2 respectively in the dataset.
这些数据的记录(x,y)位置和年龄字段中的荆棘藤条9米见方,重新调整的单位面积。根据年龄,无论是新出现的,一年或两年的分类猎犬。这些马克0,1和2分别被编码为在数据集中。
The data were recorded and analysed by Hutchings (1979) and further analysed by Diggle (1981a, 1981b, 1983), Diggle and Milne (1983), and Van Lieshout and Baddeley (1999). All analyses found that the pattern of newly emergent canes exhibits clustering, which Hutchings attributes to “vigorous vegetative reproduction”.
哈钦斯(1979)录得的数据和分析,并进一步分析Diggle(1981a,1981年b,1983年),Diggle和Milne(1983)和范·利斯豪特和巴德利(1999)。所有的分析发现,新出现的手杖展品聚类,哈钦斯归因于“积极的无性繁殖”的格局。
