We can not only read their paper but also accompanying comments from other people the Journal editor obviously asked as well as the authors rejoinder. Add in the comments and you have excellent and educative reading in the holiday season.
Andrew Gelman is obviously a top bloke. I made a comment on this superb article at his blog. Just something like what a great article or something like that.
It went into the ether.
I e-mailed him at his Uni e-mail account on boxing day. He replied on his boxing day and rectified the error.
Just goes to show a great blog run by a great bloke!!
