Hi,
I want to save the results produced by svymean. But I get confused by the
saved results.
. svyset [pweight=we] , psu(a1)
pweight is we
psu is a1
. svymean g1_1
Survey mean estimation
pweight: we Number of obs = 270805
Strata: <one> Number of strata = 1
PSU: a1 Number of PSUs = 3267
Population size = 1.705e+08
------------------------------------------------------------------------------
Mean | Estimate Std. Err. [95% Conf. Interval] Deff
---------+--------------------------------------------------------------------
g1_1 | .0289745 .0033472 .0224118 .0355373 107.8358
------------------------------------------------------------------------------
. ret li
scalars:
r(N) = 270805
r(N_strata) = 1
r(N_psu) = 270805
r(N_pop) = 270805
r(estimate) = .034090951053341
r(Var) = 1.21596276679e-07
r(Var_srs) = 1.21596276678e-07
r(errcode) = 0
My question is why r(estimate) (.034090951053341) is so different of the
estimate displayed in table (.0289745) ?
I try this with different variables and datasets and get the same problem.
Regards.
Amadou.
