This chapter discusses a successful sports bettor and how he combines knowledge of statistics and knowledge of baseball in order to find meaningful relationships in the data (and earn a lot of money along the way). To take just one example, “in September 2011, [the forecasting firm] ECRI predicted a near certainty of a ‘double dip’ recession. While the average NBA possession is worth close to one point, that exact value of expected points fluctuates moment to moment, and these fluctuations depend on what’s happening on the floor.This is part of a model used by the United States Geological Survey to calculate the probability of an earthquake occurring at any given location within a given time frame. It seems I’m missing something but I don’t get what. When it comes to economic forecasts, as Silver points out, “the true 90 percent prediction interval—based on how these forecasts have actually performed and not on how accurate the economists claim them to be—spans about 6.4 points of GDP (equivalent to a margin of error of plus or minus 3.2 percent). 3088). It is for this reason that predictive models that rely on statistics and statistics alone are often not very effective (though they do often help a seasoned expert who is able to apply insightful analysis to them).In the final stage of the book Silver explores how the lessons that he lays out can be applied to such fields as global warming, terrorism and financial markets. The Signal and the Noise Summary. Attention to detail is what we need to capture the signal in the noise (the key variable[s] in the sea of data and information that are integral in determining future outcomes), but without self-awareness and humility, we don’t even stand a chance.While self-awareness requires us to make an honest assessment of our particular biases, humility requires us to take a probabilistic approach to our predictions. A Summary of ‘The Future of the Mind: The Scientific Quest to Understand, Enhance, and Empower the Mind’ by Michio Kaku,New Podcast: A Discussion of ‘Social Physics: How Good Ideas Spread: The Lessons from a New Science’ by Alex Pentland,#53. In addition, there is a wealth of economic data available. 3070). Thanks very much.Hi Gary. 3322). 3006).And when economists aren’t busy failing to ‘predict’ recessions that have already begun, they are busy predicting ones that never arise. *For prospective buyers: To get a good indication of how this (and other) articles look before purchasing, I’ve made several of my past articles available for free. and I look forward to more of your writing.#22. Even worse, though, the evidence indicates that the prediction intervals that economists come up with are themselves not very accurate. Very well-written and easy to understand summary.Thanks Gabi. This should required reading for anyone investing in markets. ‘The Signal and the Noise: Why So Many Predictions Fail–but Some Don’t’ by Nate Silver (Penguin Press; September 27, 2012),Making decisions based on an assessment of future outcomes is a natural and inescapable part of the human condition. A Summary of ‘Capital in the Twenty-First Century’ by Thomas Piketty,New Podcast: A Discussion of ‘The Future of the Mind: The Scientific Quest to Understand, Enhance, and Empower the Mind’ by Michio Kaku,#54. 1423). The free articles are available here:This was an excellent summary and provided me with lots to think (and worry) about. Understanding these factors is integral to understanding prudent prediction-making, so we will turn our attention to them now.To begin with, the number of factors that influence the American economy are simply staggering, and truly global in scope. For instance, in a field like baseball, where wins and losses mostly comes down to two variables (the skill of the pitchers, and the skill of the hitters), and where there is an enormous wealth of precise data, prediction is relatively straightforward (but still not easy). ‘If you think this is a bad economy, you haven’t seen anything yet’” (loc. A modern alternative to SparkNotes and CliffsNotes, SuperSummary offers high-quality study guides that feature detailed chapter summaries and analysis of major themes, characters, quotes, and essay topics. Certainly puts a perspective on the presidential debates.Thanks Sandra. For example, a great subject for a project would be to look at a still-developing statistic for basketball called “expected value possession” (EVP). As Silver explains, “a prediction interval is a range of the most likely outcomes that a forecast provides for, much like the margin of error in a poll” (loc. As Silver notes, “a majority of economists did not think we were in one when the three most recent recessions, in 1990, 2001, and 2007, were later determined to have begun” (loc. Nevertheless, the author argues, within each there are certain signals that can help us make better predictions regarding them, and which should help make the world a safer and more livable place.Here is Nate Silver introducing his new book:What follows is a full executive summary of. Information on this is readily available at his blog:If there is one field where we might expect the art and science of prediction to have evolved to a fairly high level of precision it is the economy. This helped a lot! As Silver points out, though, there is a wide discrepancy across industries and also between individuals regarding just how accurate these predictions are. 3064). It starts by looking at,Chapter 2 (“Are You Smarter Than a Television Pundit?”) discusses predictions and punditry in politics.
