Dear Agge,
in the light of the details you provide the list with, unless you intend to
perform a two-sample comparison of proportions (ie, how many articles
deserved to be mentioned out of the overall number of articles submitted for
possible publication in the sample #1 and #2, respectively), your problem
seems more a matter of logistic regression  (please, see -help logit- in
Stata 9.2/SE)than power analysis.

However, should power analysis be the focus of your reserch, please take a
look at -help sampsi- in Stata 9.2/SE.

For more details about this issues, I would refer to:

HTH and Kind Regards,
Carlo

Oggetto: st: Power Analysis

Hi,

I am working on a paper where I am investigating if  researchers that
published papers  between 2000 - 2008 with mail survey data in 4 top
rated journals in economics report a certain framework (measured as 0
= mentioned ; 1 = not mentioned).

Can somebody advise me on how to undertake a power analysis for this,
please?
Many thanks in advance.

Agge
