Politicians and marketers present shoddy evidence for dubious claims all the time. But smart people make mistakes too, and when it comes to statistics, plenty of otherwise great scientists--yes, even those published in peer-reviewed journals--are doing statistics wrong."Statistics Done Wrong" comes to the rescue with cautionary tales of all-too-common statistical fallacies. It'll help you see where and why researchers often go wrong and teach you the best practices for avoiding their mistakes.In this book, you'll learn: - Why "statistically significant" doesn't necessarily imply practical significance- Ideas behind hypothesis testing and regression analysis, and common misinterpretations of those ideas- How and how not to ask questions, design experiments, and work with data- Why many studies have too little data to detect what they're looking for-and, surprisingly, why this means published results are often overestimates- Why false positives are much more common than "significant at the 5% level" would suggestBy walking through colorful examples of statistics gone awry, the book offers approachable lessons on proper methodology, and each chapter ends with pro tips for practicing scientists and statisticians. No matter what your level of experience, "Statistics Done Wrong" will teach you how to be a better analyst, data scientist, or researcher.

    But facing the sea change that AI will bring can be paralyzing. How should companies set strategies, governments design policies, and people plan their lives for a world so different from what we know? In the face of such uncertainty, many analysts either cower in fear or predict an impossibly sunny future.But in Prediction Machines, three eminent economists recast the rise of AI as a drop in the cost of prediction. With this single, masterful stroke, they lift the curtain on the AI-is-magic hype and show how basic tools from economics provide clarity about the AI revolution and a basis for action by CEOs, managers, policy makers, investors, and entrepreneurs.When AI is framed as cheap prediction, its extraordinary potential becomes clear: Prediction is at the heart of making decisions under uncertainty. Our businesses and personal lives are riddled with such decisions. Prediction tools increase productivity--operating machines, handling documents, communicating with customers. Uncertainty constrains strategy. Better prediction creates opportunities for new business structures and strategies to compete. Penetrating, fun, and always insightful and practical, Prediction Machines follows its inescapable logic to explain how to navigate the changes on the horizon. The impact of AI will be profound, but the economic framework for understanding it is surprisingly simple.

    Major retailers are predicting everything from when their customers are pregnant to when they want a new pair of Chuck Taylors. It's a brave new world where seemingly meaningless data can be transformed into valuable insight to drive smart business decisions.But how does one exactly do data science? Do you have to hire one of these priests of the dark arts, the "data scientist," to extract this gold from your data? Nope.Data science is little more than using straight-forward steps to process raw data into actionable insight. And in Data Smart, author and data scientist John Foreman will show you how that's done within the familiar environment of a spreadsheet. Why a spreadsheet? It's comfortable! You get to look at the data every step of the way, building confidence as you learn the tricks of the trade. Plus, spreadsheets are a vendor-neutral place to learn data science without the hype. But don't let the Excel sheets fool you. This is a book for those serious about learning the analytic techniques, the math and the magic, behind big data.Each chapter will cover a different technique in a spreadsheet so you can follow along: - Mathematical optimization, including non-linear programming and genetic algorithms- Clustering via k-means, spherical k-means, and graph modularity- Data mining in graphs, such as outlier detection- Supervised AI through logistic regression, ensemble models, and bag-of-words models- Forecasting, seasonal adjustments, and prediction intervals through monte carlo simulation- Moving from spreadsheets into the R programming languageYou get your hands dirty as you work alongside John through each technique. But never fear, the topics are readily applicable and the author laces humor throughout. You'll even learn what a dead squirrel has to do with optimization modeling, which you no doubt are dying to know.

    What should we do, or leave undone, in a day or a lifetime? How much messiness should we accept? What balance of new activities and familiar favorites is the most fulfilling? These may seem like uniquely human quandaries, but they are not: computers, too, face the same constraints, so computer scientists have been grappling with their version of such issues for decades. And the solutions they've found have much to teach us.In a dazzlingly interdisciplinary work, acclaimed author Brian Christian and cognitive scientist Tom Griffiths show how the algorithms used by computers can also untangle very human questions. They explain how to have better hunches and when to leave things to chance, how to deal with overwhelming choices and how best to connect with others. From finding a spouse to finding a parking spot, from organizing one's inbox to understanding the workings of memory, Algorithms to Live By transforms the wisdom of computer science into strategies for human living.

    On the beach you'll be laughing and crying between the changing of the tides. Take a ride with the main character, Lily Clarke, as you contemplate her and your own lasting legacy. Lily Clarke, the elderly mother of three dysfunctional and distant daughters, makes life altering discoveries regarding her new found wealth and other dark secrets, after she receives a diagnosis that she has a terminal illness. The challenges and decisions she must face in her final months will define her lasting legacy. To execute her plan, she invites her three dysfunctional and distant daughters to her home for a short stay to determine you will receive her new found wealth. Her plans become disrupted when dark secrets emerge, questioning her decision making and the meaning of her entire life. The book includes family dysfunction, drama, humor, an a bit of historical fiction. From the book: Chapter 1: The old saying goes that everyone has a story. Unfortunately today, October 2, 2016, Lily Elizabeth Clarke’s story was coming to a quick end. It was a sunny day at the Sacred Heart Cemetery in Dundalk, Maryland, as cars began pulling up shortly after noon for her 1:00 p.m. funeral. Old rusted smoke stacks from a bankrupt steel mill could be seen in the background of the cemetery in this gritty part of Baltimore. Neighborhoods with seventy-year-old brick weathered rowhouses surrounded the neatly manicured cemetery. The funeral was taking place exactly as Lily had arranged it. No details were left out of the planning. While she was alive, she made sure that her funeral, burial arrangements, and reading of her Last Will and Testament were organized and would be executed exactly to her wishes. No one knew what would take place over the next twenty-four hours and weeks to follow except Lily, and she was deceased. Not even her lawyer and confidant, Jake Snyder, knew all of the hidden details that Lily had intentionally failed to disclose to him; some of which had remained bottled and silenced for a lifetime. He had been Lily’s lawyer for more than twenty years, and over the next two days, he would implement her final plan exactly as she had instructed. Jake knew her for almost his whole life and thought he knew everything about her, but he didn’t know the dark secrets about her past or the ones she intended to reveal in stages following her death. The health crisis that led to Lily’s death was nothing compared to the mental struggle she faced as a result of the long forgotten secrets resurfacing during the final months of her life. Lily’s struggle whether to reveal her secrets while she was alive and how to reveal them after her death would change lives and define her legacy. Lily didn’t want to have a formal viewing at a funeral home. She wanted her funeral to be short and sweet at the gravesite, so that everyone could get on with their lives. Lily’s three daughters didn’t remain close to her after they graduated from college and settled in the state of their college alma maters. Lily was unsure why her children didn’t stay close to her. She wasn’t sure if it was her sometimes overbearing husband or the fact that her children wanted to get out of the dirty blue-collar town Baltimore was in the 1970s. Maybe they were a little rebellious, stubborn, and adventurous, all rolled into one. In truth, Lily often wondered if the secrets she harbored created impenetrable barriers in her relationship with her daughters. However, it seemed the longer they were away from Baltimore, the further they grew apart from Lily, and she didn’t have the strength or courage to correct the situation. ...

    They report to the board on the health of their workforce, their financials, their customers, and their partnerships, but rarely the health of their information assets. Corporations typically exhibit greater discipline in tracking and accounting for their office furniture than their data. Infonomics is the theory, study, and discipline of asserting economic significance to information. It strives to apply both economic and asset management principles and practices to the valuation, handling, and deployment of information assets. This book specifically shows: CEOs and business leaders how to more fully wield information as a corporate asset CIOs how to improve the flow and accessibility of information CFOs how to help their organizations measure the actual and latent value in their information assets. More directly, this book is for the burgeoning force of chief data officers (CDOs) and other information and analytics leaders in their valiant struggle to help their organizations become more infosavvy. Author Douglas Laney has spent years researching and developing Infonomics and advising organizations on the infinite opportunities to monetize, manage, and measure information. This book delivers a set of new ideas, frameworks, evidence, and even approaches adapted from other disciplines on how to administer, wield, and understand the value of information.
