Howdy Ma'am,
Just spam, I am.
Five syllables short-- Bloggerel Doggerel blog, 2007
Verse is courtesy of The Climateer, who doesn't write about climate too often, thankfully! He has a great blog description which is perpetually relevant: "In war, everything not censored is a lie."
The Climateer DOES write about investment bankers who blame statistics for their poor trading decisions... or possibly, outright deceptive practices. There was a lot of that going on in 2008. I finally hoisted some posts about double-digit standard deviations from my bookmarks and read them.
25 Sigma Event Very Unlucky
From Climateer Investor and others along the way, it seems like a 25 sigma event is impossible. "How unlucky is 25 sigma?" (2011): When Goldman Sachs was Really, Really Unlucky:
"One of the more memorable moments of last summer’s credit crunch came when the CFO of Goldman Sachs, David Viniar, announced in August that Goldman’s flagship GEO hedge fund had lost 27% of its value since the start of the year."As Mr. Viniar explained, “We were seeing things that were 25-standard deviation moves, several days in a row.”
