Truly random?!

Truly random?!

Having purchased the September edition of La Recherche because of its (disappointing!) coverage on black matter, I came by a short coverage on an Intel circuit producing “truly random” numbers… I already discussed this issue in an earlier post, namely that there is no reason physical generators are “more” random than congruential pseudo-random generators, but

Coastal

UPDATE: cce asked for a chart of coastal locations broken out by their SST component and their Land componement. That’s a little tricky, but once you figure out the mask logic its just addition and such.There are TWO masks: One mask contains ALL zeros, except for coast cells which are fraction of LAND.The other mask

Having missed the earliest entry by Radford last month, due to disconnection in Yosemite, I was stunned to read his three entries of the past month about R performances being significantly modify when changing brackets with curly brackets! I (obviously!) checked on my own machine and found indeed the changes in system.time uncovered by Radford…

MoshTemp 4.1

Replaces 4.0, minor changes made here and there. totally replaces 4.0 as the testing move forward. see 4.1 Run: DownloadAll. Run: DataSetUp. SSTTest reruns the SST analsyis and compares at HADSST2 Land1900Present: reruns the old version of program with a bench against CRU land figures. Next version will integrate more of raster to the analysis,

1936.

UPDATE: Ron Broberg has a more definitive explanation of the difference which indicates that 5sig issue is not the main cause of the difference. See his exposition here CRU, it appears, trims out station data when it lies outside 5 sigma. Well, for certain years where there was actually record cold weather that leads to

5 Sigma in CRU

UPDATE: Ron Broberg has a more definitive explanation of the difference which indicates that 5sig issue is not the main cause of the difference. See his exposition here A short update. I’m in the process of integration the Land Analysis and the SST analysis into one application. The principle task in front of me is integrating

Oh (de)bugger! Part II

In the first part of this series, I discussed some standard debugging techniques, like the use of the browser function. One of the limitations of browser is that it isn’t much help if the problem is somewhere higher up the call-stack. ... The function I’m going to show you uses sys.calls to retrieve the call stack, and sys.frames...

Now that SST has been processed with raster we can return to the land processing and put that on the same footing. To get there I’ll rebuild from scratch making some minor adjustments along the way. As we go foward the amount of code we have to write should become less and less because we

In the wake of the main machine learning NIPS 2010 meeting in Vancouver, Dec. 6-9 2010, there will be a very interesting workshop organised by Ryan Adams, Mark Girolami, and Iain Murray on Monte Carlo Methods for Bayesian Inference in Modern Day Applications, on Dec. 10. (And in Whistler, not Vancouver!) I wish I could

Statisfaction

A collective blog has been started by the statistics students and postdocs at CREST, in the wake of the Valencia meeting. It is called Statisfaction. (The Rolling Stones of Statistics?! Actually, Andrew Gelman also has a post with that title… And it is even part of the Urban Dictionnary!) Since I have no responsability nor
