[R-sig-Geo] Introducing new local spatial statistic, ELSA, and Entrogram (a variogram-like graph)

[Babak Naimi]

Dear All,

Hope you are safe and well!

I am writing to inform you that the new R package, elsa, is released on
CRAN. This package is a framework that provides the methods for quantifying
the new local spatial statictic, named "entropy-based local indicator of
spatial association" (ELSA), that can be used for both continuous and
categorical data. In addition, global spatial structure can be measured
using a new variogram-like diagram, called entrogram.

The package vignette provides a quick demonstration of some main functions
in the package:

The paper that introduces ELSA is published in the journal of spatial
statistics and is available here:

https://www.sciencedirect.com/science/article/abs/pii/S2211675318300228

The package, elsa, is also followed with functions to calculate other LISAs
and global statistics for different types of spatial datasets (i.e.,
Raster, SpatialPointsDataFrame, SpatialPolygonsDataFrame).

Best regards,

Babak Naimi
