Taking a break from his regular (brilliant) schtick, Iowahawk gives us Fables of the Reconstruction:
In short, it's a detailed how-to-guide for replicating the climate reconstruction method used by the so-called "Climategate" scientists. Not a perfect replication, but a pretty faithful facsimile that you can do on your own computer, with some of the same data they used.
It would appear that the boy knows a thing or two about statistics.
I'm an engineer who uses baby statistics by comparison. While Iowahawk's disassembly of the CRU data will be of interest to technical folks, even non-technical types should find a new appreciation of what goes in to "adding value" to raw data measurements, and what a big deal it is that not all the raw data still exists.
What the leaked emails reveal, among other things, is some of that bit of principal component sausage making. But more disturbing, they reveal that the actual data going into the reconstruction model -- the instrumental temperature data and the proxy variables themselves -- were rife for manipulation. In the laughable euphemism of Philip Jones, "value added homogenized data."
