Webroaming.entropy. This is an application of the Shannon entropy measure to spatial paths. In Rtrack, it is estimated by calculating a density map with a 50 \(\times\) 50 grid (and a bandwidth of 1/50) which is clipped to the bounds of the arena. This gives a computationally fast estimate of \(p\); the likelihood of the path passing through any one of the grid cells.
