Judith Curry and JEG have expressed an interest in talking about Mann et al 2007, Robustness of proxy-based climate field reconstruction methods, JGR pdf. This is successor article to Mann et al, 2005, Testing the Fidelity of Methods Used in Proxy-Based Reconstructions of Past Climate, pdf. Looking past the annoying and amusing faults, here are some […]

Benchmarking from VZ Pseudoproxies

Jul 4, 2006 – 2:09 PM

Von Storch et al 2004 advocated using climate models to generate pseudoproxies to test the properties of proposed multivariate methods. Hardly unreasonable. I might argue that these are long-winded ways of generating proxy series with certain kinds of temporal and spatial covariance structures, but there’s much to be said for testing methods on some standard […]
