Hi,
I have 3 questions:
- I am using povdeco to compute poverty lines.
I could retrieve the 3 poverty measures when I use povdeco
without the by() option, through the macros $FGT0 $FGT1 $FGT2.
But I have a problem retrieving these measures when I apply the by()
option.
The "ret li" returns only the total number of observations (r(N)).
How to retrieve the poverty rates for each value (ie the X1, X2, ... X6 below)?
povdeco pcexp [aw=wei], pl(20000)
ret li
local P0=$FGT0
local P1=$FGT1
local P2=$FGT2
povdeco pcexp [aw=wei], pl(20000) by(urbrur)
P0 P1 P2
-------------------------------------------------------------------
Urban X1 X2 X3
Rural X4 X5 X6
ret li
. r(N)=7890
Actually, I am getting around by doing:
povdeco pcexp [aw=wei], pl(20000) by(region)
povdeco pcexp [aw=wei] if region==1, pl(20000)
(save results in a macro)
povdeco pcexp [aw=wei] if region==2, pl(20000)
povdeco pcexp [aw=wei] if region==3, pl(20000)
etc.,
but this could be painful if we have many regions.
Could anyone help for this please?
- My second question is more general
when I tab 2 variables, how to retrieve the frequences (X1 X2 X3 X4)?
It would be nice if these values where left behind after tab (as well as the
frequences, cumulative frequencies, etc...)
tab v1 v2
v2
| 0 1
--------|-------------------------------
v1 0 | X1 X2
1 | X3 X4
- My third question: I have two different results when I do the following (with
or without weights):
bys(V1): su V2
collapse (mean) V2, by(V1)
The means in collapse are greater (rounded?). What is happening here?
Sorry for not providing concrete examples. I am using two computers and this
one (with internet connection) does not have stata installed. So I hope you
have clear understanding of my questions.
Best regards.
Amadou.
