Jackman only just released his data now (after twittering with me, incidentally, I was able to explain why his R Brier score wasn’t matching his hand-calculated Brier score) because he forgot to send it to me last night; and I’m running on fumes—we started this project from scratch yesterday at 5PM and I’ve been working on it ever since. EDIT: Looks like all the kerfluffle of new Brier/RMSE scores prodded Sam Wang into releasing his precise predictions too! Neat. EDITEDIT: I’ve gotten Jackman’s data, incorporated it, discovered an error in my own data, differed with Jackman, learned he regarded 5 states as such a sure thing he didn’t include probabilities while I had simply put in NAs, and now we’ve converged on his Brier score. Phew! His current Brier score is 0.009713686, a bit worse than Silver’s 0.009113725, and both seem to be outperformed by Drew Linzer’s 0.003843257. Wang seems to’ve released the data, but the CSV is unlabeled and I have no idea what half the columns mean...
I’d also like to include a random-guesser equivalent for RMSE… Tomorrow.

A better Brier random guesser and its RMSE equivalent are now in the R doc and hopefully the blog post will be updated shortly.
