SpatEntropy:Spatial Entropy Measures
The heterogeneity of spatial data presenting a finite number of categories can be measured via computation of spatial
entropy. Functions are available for the computation of the
main entropy and spatial entropy measures in the literature.
They include the traditional version of Shannon's entropy
(Shannon, 1948 <doi:10.1002/j.1538-7305.1948.tb01338.x>),
Batty's spatial entropy (Batty, 1974
<doi:10.1111/j.1538-4632.1974.tb01014.x>), O'Neill's entropy
(O'Neill et al., 1998 <doi:10.1007/BF00162741>), Li and
Reynolds' contagion index (Li and Reynolds, 1993
<doi:10.1007/BF00125347>), Karlstrom and Ceccato's entropy
(Karlstrom and Ceccato, 2002
<https://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-61351>),
Leibovici's entropy (Leibovici, 2009
<doi:10.1007/978-3-642-03832-7_24>), Parresol and Edwards'
entropy (Parresol and Edwards, 2014 <doi:10.3390/e16041842>)
and Altieri's entropy (Altieri et al., 2018,
<doi:10.1007/s10651-017-0383-1>). Full references for all
measures can be found under the topic 'SpatEntropy'. The
package is able to work with lattice and point data. The
updated version works with the updated 'spatstat' package (>=
3.0-2).
