%description
Computes segregation indices, including the Index of Dissimilarity, as
well as the information-theoretic indices developed by Theil (1971)
<isbn:978-0471858454>, namely the Mutual Information Index (M) and Theil's
Information Index (H). The M, further described by Mora and Ruiz-Castillo
(2011) <doi:10.1111/j.1467-9531.2011.01237.x> and Frankel and Volij (2011)
<doi:10.1016/j.jet.2010.10.008>, is a measure of segregation that is
highly decomposable. The package provides tools to decompose the index by
units and groups (local segregation), and by within and between terms. The
package also provides a method to decompose differences in segregation as
described by Elbers (2021) <doi:10.1177/0049124121986204>. The package
includes standard error estimation by bootstrapping, which also corrects
for small sample bias.
