Thanks, for the links, especially the wikipedia article is pretty clear.
It looks like datasets in R (based on published or publicly available
information) is pretty much free game, since we only use the facts and
not the R code.

Do we need a disclaimer, don't look at the data if you are in Australia?

In statsmodels, we don't just want to have tests, we also want to
verify that we can replicate known results and for illustration as
part of the documentation. (maybe it's functional/acceptance tests
versus unit tests)
