Re: st: Using the 2008 American National Election Study with Stata v.11

Is anyone familiar with using the 2008 NES with Stata? I have two
specific questions:
1. Which weight command is most appropriate for the data? Based on the
Stata UG, it seems that the -iweight- syntax is most appropriate, but is
that correct?
I am not familiar with the data set, but I would be amazed if
iweights were the way to go. My guess is you want pweights. googling
around found this recent paper:
ftp://ftp.electionstudies.org/ftp/nes/bibliography/documents/nes012427.pdf
If you google around some more though, maybe you can find something
easier to wade through; it is nice when a data set explicitly tells
you how to set the weights in Stata.
2. In the ANES 2008 user guide, we are advised, "due to the complex
sample design of the ANES, sampling errors and related statistics
(including confidence intervals, p-values, t-tests, and all other tests
of statistical significance) should not be calculated using methods
intended for simple random samples." In light of this, which would be
the appropriate statistics to use in Stata?
I think the correct question is not what statistics should I use, but
what statistical methods should I use to get the correct
statistics. Since you have Stata 11, you should also have the SVY
manual available in pdf form. Just click help/ PDF
documentation. If bookmarks are open then on the left hand side
you'll see the svy manual. After you've gone over the opening
explanatory material, the section on svy estimation will highlight
the many commands you have available. You'll probably want commands
like svy: tabulation, svy: mean, svy: regress, svy: logit, etc.
