Eli Rabett Eli Rabett Eli Rabett is a not quite failed professorial techno-bunny, a chair election from retirement, at a wanna be research university that has a lot to be proud of but has swallowed the Kool-Aid. The students are naive but great and the administrators vary day-to-day between homicidal and delusional

toto said… My understanding is that "short-centering" was actually a bona-fide bug. If you’re computing a covariance matrix by simply multiplying the data with its own inverse, "short-centering" the data around the recent past will produce "fake covariance" of all series with the hockey-stickish series (with a negative sign, but that’s irrelevant).The actual PCs being computed are the same, but the ‘hockey-stickish’ ones now seem to explain much more of the variance – spuriously so.Unfortunately the auditor-in-chief proceeded to introduce a bug of his own, by keeping the same number of PCs as Mann after full-centering the matrix, even though by then you need to include more PCs to capture sufficient variance
Tweet One of the joys about having a publishing or public relations office is that news is not judgement, indeed to believe Andy Revkin, that would be evil issue advocacy.
See APS policy review "The members of the Subcommittee are: Steven Koonin (chair), Phillip Coyle, Scott Kemp, Tim Meyer, Robert Rosner and Susan Seestrom."(That was not in WSJ, but I suspect will appear, given some of the other APS history below.)Arthur mentioned that. People might explore that, and check out the bios of those who attended the workshop, several of whom are quite famous for uncertainty.I’m an APS (and APS GPC ) member, and I certainly have not yet seen a statement put up for review
