Nate Silver, the Signal and the Noise, why so many predictions fail but some dont.
Figure I-1: european book production As was pdfzip the case during the early days of the World Wide Web, however, the quality of the information noise was highly varied.
Nate Silver: began by compiling spreadsheets of baseball statistics.
In a promising start, he claims that his model based on a theorem inspired.Instead, they were noise luxury nate items for the nobility, produced one copy at signal a time by scribes.3 The going rate for reproducing a single manuscript was about one florin (a gold coin worth about 200 in todays dollars) per five pages,4 so a book like the.It was hard to silver tell the signal from the noise.For that reason, nate it could turn out to be one of the more momentous books of the decade.His signature approach is to concentrate enormous amounts of data on questions that lend themselves to pious blather.This is a book about how we learn, one step at a time, to come to knowledge of the objective world, and why we sometimes take a step back.It turns out were not even close to predicting the next catastrophic earthquake or the spread of the next killer bird flu, despite the enormous amounts of brainpower trained on these questions in the past few decades.
These triumphs have built Silver a loyal following among fantasy-baseball aficionados and the silver political buffs who flock to his New York Times blog, FiveThirtyEight.
All that information signal in all those books ought to have helped us to plan our lives and profitably predict signal the worlds course.
Predictions work best when they are 1) probabilistic (i.e., express a range of possibilities and assign probabilities for each 2) when they use as much information-both statistical and analytical-as possible; and 3) when they are continually revised to account for new information.The following year, he took up poker in his spare time and quit his job after winning 15,000 in six months.What we have is a growing sense of intellectual nihilism.Silvers volume light is more like an engagingly written users manual, with forays into topics like dynamic nonlinear systems (the guts of chaos theory) and Bayess theorem (a tool for figuring out how likely a particular hunch is right in light of the evidence we observe).This time it did not take three hundred years before the growth in information technology began to produce tangible benefits to human society.When the worldwide media was universally proclaiming the race too close to call and the pundits were deriding mathematical models, m steadily argued that the odds made clear that Obama would win.Business Cycle Expansions and Contractions National Bureau launchinfsection of Economic Research,.After windir the first plane hit, the revised probability nate of a terror attack comes out.In 1971, for instance, it was claimed that we would be able to predict earthquakes within a decade,29 a problem that we are no closer to solving forty years later."Much of the most thoughtful work I have found on signal the use and abuse of statistical models, and on the proper role of prediction, comes from people in the medical profession Silver reports.In 2003, bored at a consulting job, I designed a system called pecota, which sought to predict the statistics of Major League Baseball players.But _The Signal and the Noise_ is a much more substantial book than, say, _The Blac Nate Silver has done an incredible (and, quite possibly an unpredictable) thing with _The Signal and the Noise He has written an extremely good book when he didn't even.Throughout it all, he reminds us that human beings are pattern-seeking animals and that we are just as likely to build patterns where none exist as we are to find the correct patterns and harness their predictive capacity.In 2008, I founded the Web site FiveThirtyEight, which sought to forecast the upcoming election.
