Note that you should either use Stata SE (for large
datasets) or Stata IC (Standard). Small Stata is too limited to
handle most of the datasets. The website contains useful
links, including to the Stata Listserve maintained by Harvard School
of Public Health.
The most useful and comprehensive guide to all the
commands you will use for frequencies, crosstabs, charts, means,
factords analysis and OLS regressions. Highly recommended. pp640
IQSS Dataverse Network is the main source for
quantitative survey datasets. You can search Dataverse for all
datasets but you will need to try different terms and keywords to
find exactly the right file. You will need to login to download
datasets.
