Mobility entropy

Description

In Song's paper, three kinds of entropy are involved to investigate the predictability of human mobility, i.e., random entropy $S^rand$, spatial entropy $S^unc$ and spatio-temproal entropy $S_i$.

Usage

entropy.spacetime(x, y = NULL)

Arguments

x, y	A chronologically ordered sequence of visited locations. The sequence is given by a vector (e.g. location names) or two vectors of location coordinates (e.g., latitude and longitude values).

Value

The entropy value in bits.
