Dear Stata users,
is there a command to derive in Stata 10 with standard errors for Foster, Greer and Thorbecke type of poverty measurements? The poverty rate a such I edrived as following (for one specifc region) poverty pcexp if region==1 , line(9500.4) h ------------------------------------------------------------------------------ Poverty measures of pcexp ------------------------------------------------------------------------------ Your selection is made of 155 observations. The following poverty analysis has been using the 155 non-missing observations for pcexp in your selection. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The poverty line is set at 9500.4 units ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Headcount ratio % 79.355 ------------------------------------------------------------------------------ Every comment is most appreciated.

There are some commands by Dean Jolliffe with some Russian folks
(-findit sepov-). I thought Stephen Jenkins had something about that, too, but I cannot locate it in -findit poverty- output -- it might've been s.e.s for inequality measures, rather. You can get pretty much anything you need using -mean- of appropriately generated variables and -nlcom- to combine them into FGT measure of interest. What's more, that will also be appropriate for complex survey designs -- I have serious doubts that you will have access to any sort of census data in Subsaharan Africa. Can you possibly comment as to why do you need s.e.s on your poverty measures? It is rather unusual that somebody wants them... although it pleases my inner statistician to see people do that :)).

you can use the DASP package developed by A. Araar and J-Y Duclos
available at http://132.203.59.36/DASP/index.html you can estimate various poverty inequality measure with their s.e and taking into account the sampling design. Concerning the remark of Stas Kolenikov I note that std-err of poverty measure are required by most journal and policy maker to assess the effect of sampling variability on poverty and inequlity measure.

Well in that whole DASP manual, they never discuss how they get the
standard errors. If that were a Stata Journal submission, it would probably be returned with a request for Methods and Formulas section. It is not mentioned in their huge analytical manual, either -- although of course that's a very useful summary of all things in distributional economics, with all the right references. And unfortunately I've seen more than once that something produced and promoted by the World Bank eventually gets rebutted for not being technically/statistically/econometrically solid -- maybe for the simple reason that it does not have to pass peer review and be presented at half a dozen seminars with critical audience to appear as a working paper (and it does not help much that the number of people who understand both economics of distribution and analysis with complex survey data is miserably small). So if I were using this package I would at least make sure that it produces correct standard errors by cross-checking with other procedures. Of course producing standard errors is a useful practice. But even computing the standard error of a difference of two say Gini coefficients or FGT indices between two surveys may not be that easy if the samples are not perfectly independent. Just a word of caution. On 12/5/08, Abdel Rahmen El Lahga <[hidden email]> wrote: > you can use the DASP package developed by A.

It looks to me like you want % with pcexp<=9500.4 --is that right? If so, just:
g byte poverty=(pcexp<=9500.4) if pcexp<. g byte reg1=region==1 svy, subpop(reg1): tab poverty, se svy, subpop(reg1): tab poverty, ci svy: tab region poverty, row ci If you do not have survey data, just svyset, srs first.
