Jeff Pitblado has kindly confirmed my guess that if you
want -sepov- to be up-to-date it needs to use
a call to -svy: mean-.
Here is a second version of -sepov2- (still
untested!):
*! sepov2 1.1.0 NJC 19 Oct 2006
* !!! note: assumes variables p0, p1, p2, p`alpha' do not exist !!!
* sepov 1.1.0 27/09/99 sepov.ado [STB-51: sg117]
* Dean Jolliffe, Anastassia Semykina
program sepov2
version 9
syntax varlist [pweight iweight] [if] [in] [, ///
Povline(string) Alpha(real 0) * ]
marksample touse
qui count if `touse'
if r(N) == 0 error 2000
if `alpha' < 0 {
di as err "negative alpha is not allowed"
exit 198
}
foreach v of local varlist {
if `"`: variable label `v''"' != "" {
local lbl `": `: variable label `v''"'
}
else local lbl
gen p0 = `v' < `povline'
gen p1 = p0 * (1 - `v'/`povline')
gen p2 = p0 * (1 - `v'/`povline')^2
di as txt _n(2) "Poverty measures for `v'`lbl'"
if !inlist(`alpha', 0, 1, 2) {
gen p`alpha'= p0 * (1 - `v'/`povline')^`alpha'
local svyvars p0 p1 p2 p`alpha'
}
else local svyvars p0 p1 p2
svy : mean `svyvars' if `touse' [`weight'`exp'], `options'
drop `svyvars'
}
end
