The book emphasizes Silver's skill, which is the practical art of mathematical model building using probability and statistics.

Silver takes a big-picture approach to using statistical tools, combining sources of unique data e. The book includes richly detailed case studies from baseball, elections, climate change , the financial crash, poker, and weather forecasting. These different topics illustrate different statistical principles.

For example, weather forecasting is used to introduce the idea of "calibration," or how well weather forecasts fit actual weather outcomes. There is much on the need for improved expressions of uncertainty in all statistical statements, reflecting ranges of probable outcomes and not just single "point estimates" like averages.

The shares of the popular vote similarly are ranges including outcomes in which Romney gets the most votes. What is highly probable is that the voting shares are in these ranges, but not whose share is highest; that's another probability question with closer odds.

From such information, it's up to the consumer of such statements to use that information as best they can in dealing with an uncertain future in an age of information overload.

That last idea frames Silver's entire narrative and motivates his pedagogical mission. Silver rejects much ideology taught with statistical method in colleges and universities today, specifically the "frequentist" approach of Ronald Fisher , originator of many classical statistical tests and methods.

The problem Silver finds is a belief in perfect experimental, survey, or other designs, when data often comes from a variety of sources and idealized modeling assumptions rarely hold true. Often such models reduce complex questions to overly simple "hypothesis tests" using arbitrary "significance levels" to "accept or reject" a single parameter value. In contrast, the practical statistician first needs a sound understanding of how baseball, poker, elections or other uncertain processes work, what measures are reliable and which not, what scales of aggregation are useful, and then to utilize the statistical tool kit as well as possible.

Silver believes in the need for extensive data sets, preferably collected over long periods of time, from which one can then use statistical techniques to incrementally change probabilities up or down relative to prior data.

This "Bayesian" approach is named for the 18th century minister Thomas Bayes who discovered a simple formula for updating probabilities using new data. For Silver, the well-known method needs revitalizing as a broader paradigm for thinking about uncertainty, founded on learning and understanding gained incrementally, rather than through any single set of observations or an ideal model summarized by just a few key parameters. Part of that learning is the informal process of changing assumptions or the modeling approach, in the spirit of a craft whose goal is to devise the best betting odds on well-defined future events and their outcomes.

Climate scientist Michael E. Mann criticized the book for analyzing the "hard science" physical phenomena of climate trends with the same approach as used to analyze the social phenomena of voter preferences, which he characterized as "laden with subjective and untestable assumptions". However, he purposefully leaves out the mathematics. In , after his triumph of predicting the outcome of the last two presidential elections and selling his "fivethirtyeight" blog to the New York Times, Nate Silver accomplished what is almost impossible.

In his recent book The Signal and the Noise, he correctly describes the discipline of making predictions, without explicitly invoking the math. He accomplishes this feat even though the prediction methods he describes require more than one kind of mathematics. By leaving out the math, he has reached a broad audience with a compelling book with lots of examples.

Every time we choose a route to work, decide whether to go on a second date, or set aside money for a rainy day, we are making a prediction about the future. Yet from the financial crisis to ecological disasters, we routinely fail to foresee hugely significant events, often at great cost to society.

Look Inside. Sep 27, Minutes Buy. 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.

Unfortunately, people tend to be terrible forecasters. As Wharton professor Philip Tetlock showed in a landmark study, even experts' predictions are only slightly better than chance.

The Signal and the Noise: Why So Many Predictions Fail — but Some Don't

Когда Мидж проходила мимо, Бринкерхофф по выражению ее глаз понял, что она и не думает сдаваться: чутье не позволит ей бездействовать. Бринкерхофф смотрел на массивную фигуру директора, возвышающуюся над письменным столом. Таким он его еще никогда не. Фонтейн, которого он знал, был внимателен к мелочам и требовал самой полной информации. Он всегда поощрял сотрудников к анализу и прояснению всяческих нестыковок в каждодневных делах, какими бы незначительными они ни казались. И вот теперь он требует, чтобы они проигнорировали целый ряд очень странных совпадений. Очевидно, директор что-то скрывает, но Бринкерхоффу платили за то, чтобы он помогал, а не задавал вопросы.

После каждой из них следовал один и тот же ответ: ИЗВИНИТЕ. ОТКЛЮЧЕНИЕ НЕВОЗМОЖНО Сьюзан охватил озноб. Отключение невозможно. Но. Увы, она уже знала ответ.

Выслушай меня внимательно, - попросил Стратмор. Сьюзан была ошеломлена. ТРАНСТЕКСТ еще никогда не сталкивался с шифром, который не мог бы взломать менее чем за один час. Обычно же открытый текст поступал на принтер Стратмора за считанные минуты. Она взглянула на скоростное печатное устройство позади письменного стола шефа. В нем ничего не .

Как они этого сразу не заметили. Северная Дакота - вовсе не отсылка к названию американского штата, это соль, которой он посыпал их раны. Он даже предупредил АНБ, подбросив ключ, что NDAKOTA - он .

Должно быть, это какая-то ошибка. Следопыт показывал адрес, не имеющий никакого смысла. Взяв себя в руки, она перечитала сообщение. Это была та же информация, которую получил Стратмор, когда сам запустил Следопыта.

 - Чатрукьян уже, надеюсь, ушел. - Не знаю, я его не видела. - Господи Иисусе, - простонал Стратмор.  - Ну прямо цирк.  - Он провел рукой по подбородку, на котором темнела полуторасуточная щетина.

 - Он заверил меня, что ТРАНСТЕКСТ в полной исправности. Сказал, что он взламывает коды каждые шесть минут и делал это даже пока мы с ним говорили. Поблагодарил меня за то, что я решил позвонить. - Он лжет, - фыркнула Мидж.
