pov {ineq} | R Documentation |
computes the poverty of an (income) vector according to the specified poverty measure
pov(x,k,parameter=1,type=c("Watts", "Sen", "Foster")) Watts(x,k) Sen(x,k) Foster(x,k,parameter=1)
x |
a vector containing at least non-negative elements |
k |
a constant giving the absolute poverty boundary |
parameter |
parameter of the poverty measure |
type |
character string giving the measure used to compute poverty coefficient must be one of the strings in the default argument (the first character is sufficient). defaults to "Watts". |
pov
is just a wrapper for the poverty measures of
Watts
, Sen
and Foster
(Foster / Greer / Thorbecke).
Foster
gives for parameter 1 the head count ratio and for
parameter 2 the poverty gap ratio.
the value of the poverty measure
