Rapid responses are electronic letters to the editor. They enable our users to debate issues raised in articles published on thebmj.com. Although a selection of rapid responses will be included online and in print as readers' letters, their first appearance online means that they are published articles. If you need the url (web address) of an individual response, perhaps for citation purposes, simply click on the response headline and copy the url from the browser window. Letters are indexed in PubMed.
I second Perneger's (and Galton's) call for data sharing.
Galton himself was the first to practice what he preached. He shared
the family data that he collected (and paid the families 500 pounds for!)
to derive the "regression to mediocrity" equation linking the stature of
parents and their offspring.
For more than a century, we were only aware of the "uni-sexed" and
"family-de-identified" data shown as frequencies in a 2-way table in his
papers and book. Meanwhile, all along, the raw data lay in a (now-frail)
notebook "Copies of original data: RFF" that he had had deposited in the
Galton Papers. Since 2004, with the approval of University College London,
digital photographs of the pages of his notebook of heights, along with an
electronic copy of the numbers they contain, and some other related
photographs, have been available, for all to use, at http://www.biostat.mcgill.ca/hanley/galton.
