ineq
is just a wrapper for the inequality measures Gini
,
RS
, Atkinson
, Theil
, Kolm
,var.coeff
,
entropy
. Gini
is the Gini coefficient, RS
is the the Ricci-Schutz
coefficient (also called Pietra�s measure), Atkinson
gives
Atkinson�s measure and Kolm
computes Kolm�s measure.
If the parameter in Theil
is 0 Theil�s entropy measure is
computed, for every other value Theil�s second measure is
computed.
ineq(x, type="var")
and var.coeff(x)
respectively
compute the coefficient of variation, while
ineq(x,type="square.var")
and var.coeff(x, square=T)
compute the squared coefficient of variation.
entropy
computes the generalized entropy, which is for
parameter 1 equal to Theil�s entropy coefficient and for parameter
0 equal to the second measure of Theil.
