A Significance Test for Inferring Affiliation Networks from Spatio-Temporal Data
Fig 1
An example of high-resolution positional data collected through GPS technology.
This example illustrates the movement patterns of a single sheep from a flock of Merino sheep. The data is split into the period in the holding pen, the period in the race (between the holding pen and the field) and the period in the field. The holding pen and the field are illustrated in the figure on the left, while the tracks of the animal are illustrated (in blue) in the figure on the right. The data set for an entire flock consists of such a trajectory sequence for each individual in the flock. More details of this data set can be found in the data collection section of the paper. Given such a set of movement patterns, the aim of this paper is to provide tools to infer the affiliation network of the group.
