    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.

    Brick-and-mortar has shifted to online, while online is shifting into pop-up storefronts. Virtual stores in subway platforms and airports are offering new levels of convenience for harried commuters. High Street and Main Street are becoming the stuff of nostalgia. The Big Box is losing ground to new models that attract consumers through their most-trusted assistant--the smartphone. What's next?

    This is the gripping tale of Britain's top investor's fall from grace and the shattering consequences. The proud owner of a sprawling £14m estate in the Cotswolds, boasting a stable of eventing horses, a fleet of supercars and neighbouring the royal family, Neil Woodford was the most celebrated and successful British investor of his generation. He spent years beating the market; betting against the dot com bubble in the 1990s and the banks before the financial crash in 2008, making blockbuster returns for his investors and earning himself a reputation of 'the man who made Middle England rich'. As famous for his fleet of fast cars and ostentatious mansions, he was the rockstar fund manager that had the lifestyle to match. But, in 2019, after a stream of poorly-judged investments, Woodford's asset management company collapsed, trapping hundreds of thousands of rainy-day savers in his flagship fund and hanging £3.6bn in the balance. In Built on a Lie, Financial Times reporter Owen Walker reveals the disastrous failings of Woodford, the greed and opulence at the heart of his operation, the flaws of an industry in thrall to its star performers and the dangers of limited regulation. With exclusive access to Woodford's inner circle, Walker will reveal the full, jaw-dropping story of Europe's biggest investment scandal in a decade.
