I notice that the phrase "spaghetti diagram" is catching on a little. In connection with MM05, we archived 100 simulated PC1s, using the weird method of MB98. Just for fun, here’s a spaghetti diagram from 6 of these, chosen from the 100 at random, with 25-year smooths. You’ll see why I’m pretty unimpressed with spaghetti diagrams as a statistical technology. Given the proliferation of spaghetti diagrams, this obviously needs to be written up. I can splice the instrumental record and it will probably look better than the current round of spaghetti diagrams. The underlying issue is that the Mann’s PC methodology is only one form of cherry-picking, although it is a mechanized and very efficient form of cherry-picking.
