去僞存真,透過現象看到本質這種道理誰都懂,但是懂得道理又能怎麼樣,看瞭那麼多數據事例和例證,下一次還是會齣錯,就像人生中很多彆的事情一樣,懂瞭道理,和知道怎麼做,該去怎麼做,具體怎麼做不是一迴事:p
評分Case挺多,key message沒啥特彆新意。無非就是基於動態係統隨時修正,充分考慮樣本之間的關係假設和結果概率等。

評分I CB158 S54 2012, business type
Nate Silver is a statistician, writer, and founder of The New York Times political blog FiveThirtyEight.com. Silver also developed PECOTA, a system for forecasting baseball performance that was bought by Baseball Prospectus. He was named one of the world’s 100 Most Influential People by Time magazine. He lives in Brooklyn, New York.
"Nate Silver's The Signal and the Noise is The Soul of a New Machine for the 21st century."
—Rachel Maddow, author of Drift
Nate Silver built an innovative system for predicting baseball performance, predicted the 2008 election within a hair’s breadth, and became a national sensation as a blogger—all by the time he was thirty. The New York Times now publishes FiveThirtyEight.com, where Silver is one of the nation’s most influential political forecasters.
Drawing on his own groundbreaking work, Silver examines the world of prediction, investigating how we can distinguish a true signal from a universe of noisy data. Most predictions fail, often at great cost to society, because most of us have a poor understanding of probability and uncertainty. Both experts and laypeople mistake more confident predictions for more accurate ones. But overconfidence is often the reason for failure. If our appreciation of uncertainty improves, our predictions can get better too. This is the “prediction paradox”: The more humility we have about our ability to make predictions, the more successful we can be in planning for the future.
In keeping with his own aim to seek truth from data, Silver visits the most successful forecasters in a range of areas, from hurricanes to baseball, from the poker table to the stock market, from Capitol Hill to the NBA. He explains and evaluates how these forecasters think and what bonds they share. What lies behind their success? Are they good—or just lucky? What patterns have they unraveled? And are their forecasts really right? He explores unanticipated commonalities and exposes unexpected juxtapositions. And sometimes, it is not so much how good a prediction is in an absolute sense that matters but how good it is relative to the competition. In other cases, prediction is still a very rudimentary—and dangerous—science.
Silver observes that the most accurate forecasters tend to have a superior command of probability, and they tend to be both humble and hardworking. They distinguish the predictable from the unpredictable, and they notice a thousand little details that lead them closer to the truth. Because of their appreciation of probability, they can distinguish the signal from the noise.
With everything from the health of the global economy to our ability to fight terrorism dependent on the quality of our predictions, Nate Silver’s insights are an essential read.

評分1、大数据时代,信号与噪声并存,而且噪声往往容易掩盖信号,对数据未进行滤波分析的情况下贸然进行数据拟合,将造成模型的严重失真。 2、因果性与相关性并非等同,很多情况下,我们将相关性与因果性混为一谈。 3、作者在本书中的主旨在于对信号与噪声的关系进行分析,然而由于...
