Yes, it's true that the devil can be in the details What are the best characteristics of an excellent data scientist or statistician? You are mistaken if you thought about mathematical knowledge or mastery of data tools! Those receiving salaries of up to thousands of reais per day of work have something in common: they are humble and know that they are never sure, but they persistently know how to “create” bridges between information repositories or even departments of people. This same data scientist will have to break boundaries between departmental areas that do not speak to each other to reach a common and ideal result for the short, medium or long term. Each of these professionals who share their knowledge in this book presents their own experience of how to involve data, people, and techniques. At times, this same data scientist acts as a “data therapist”, understanding your past and traumas, going back in time to understand your evolution to transform this same data into “digital wisdom” and get the best out of it. A company that does not apply data science with CRM, Customer Experience, Commercial Intelligence and other concepts to constantly reformulate itself, as a brand and product, may have its days numbered. Show your data to an extremely qualified data scientist, and he or she will tell you what future your company will have. Would your company have the courage to have a professional with this skill? The market is looking for you: data scientist.

When you know the cause of an event, you can affect its outcome. This accessible introduction to causal inference shows you how to determine causality and estimate effects using statistics and machine learning. A/B tests or randomized controlled trials are expensive and often unfeasible in a business environment. Causal Inference for Data Science reveals the techniques and methodologies you can use to identify causes from data, even when no experiment or test has been performed. In Causal Inference for Data Science you will learn how to: • Model reality using causal graphs • Estimate causal effects using statistical and machine learning techniques • Determine when to use A/B tests, causal inference, and machine learning • Explain and assess objectives, assumptions, risks, and limitations • Determine if you have enough variables for your analysis It’s possible to predict events without knowing what causes them. Understanding causality allows you both to make data-driven predictions and also intervene to affect the outcomes. Causal Inference for Data Science shows you how to build data science tools that can identify the root cause of trends and events. You’ll learn how to interpret historical data, understand customer behaviors, and empower management to apply optimal decisions. About the technology Why did you get a particular result? What would have lead to a different outcome? These are the essential questions of causal inference. This powerful methodology improves your decisions by connecting cause and effect—even when you can’t run experiments, A/B tests, or expensive controlled trials. About the book Causal Inference for Data Science introduces techniques to apply causal reasoning to ordinary business scenarios. And with this clearly-written, practical guide, you won’t need advanced statistics or high-level math to put causal inference into practice! By applying a simple approach based on Directed Acyclic Graphs (DAGs), you’ll learn to assess advertising performance, pick productive health treatments, deliver effective product pricing, and more. What's inside • When to use A/B tests, causal inference, and ML • Assess objectives, assumptions, risks, and limitations • Apply causal inference to real business data About the reader For data scientists, ML engineers, and statisticians.

In the sun-baked streets of Culiacán, the heartland of the Sinaloa Cartel, a young, brilliant architect named Rodrigo Rios is facing the quiet desperation of a life unfulfilled. Weighed down by debt and disillusioned with the legitimate world, he accepts an offer from his childhood friend, the son of the enigmatic cartel leader Isidro "El Viejo" Cardenas. The offer is simple: use his intelligence and quiet demeanor in service of the cartel. It is a choice that will lead him down a path of unimaginable power and spectacular ruin. Christened "El Fantasma," Rodrigo sheds his old life and becomes the most feared and innovative commander in the organization. He forges an elite crew of assassins, Los Espectros, and wages a brutal war against his rivals. But his true genius lies not in violence, but in branding. He creates a public persona, "Comandante Fantasma," an anonymous narco-celebrity who broadcasts a life of impossible luxury and power on social media. His feed—a curated gallery of supercars, pet tigers, and custom weapons—becomes a viral sensation, making him a legend and a powerful recruiting tool for a new generation. He is the influencer sicario, a king ruling a digital empire. His rise, however, is being meticulously documented by an unseen enemy. In a windowless room in San Diego, DEA Agent David Miller sees the ghost’s digital footprint not as a myth, but as a trail of evidence. As Rodrigo’s fame makes him a target for both jealous rivals and the law, he is drawn into a high-stakes international game of cat and mouse, from the battlefields of Mexico to the luxury suites of Europe. Based on a shocking true story, The Ghost of Culiacán is a relentless, action-packed thriller about a new kind of criminal for the modern age—a man who built a global empire on a social media account, only to discover that every post, every follower, and every ‘like’ was another bar in the cage being built around him.

This book addresses data quality management for data markets, including foundational quality issues in modern data science. By clarifying the concept of data quality, its impact on real-world applications, and the challenges stemming from poor data quality, it will equip data scientists and engineers with advanced skills in data quality management, with a particular focus on applications within data markets. This will help them create an environment that encourages potential data sellers with high-quality data to join the market, ultimately leading to an improvement in overall data quality. High-quality data, as a novel factor of production, has assumed a pivotal role in driving digital economic development. The acquisition of such data is particularly important for contemporary decision-making models. Data markets facilitate the procurement of high-quality data and thereby enhance the data supply. Consequently, potential data sellers with high-quality data are incentivized to enter the market, an aspect that is particularly relevant in data-scarce domains such as personalized medicine and services. Data scientists have a pivotal role to play in both the intellectual vitality and the practical utility of high-quality data. Moreover, data quality control presents opportunities for data scientists to engage with less structured or ambiguous problems. The book will foster fruitful discussions on the contributions that various scientists and engineers can make to data quality and the further evolution of data markets.

A gripping look at gravitational wave research and what it says about scientific discovery and the future of the scientific community. “This fine book pairs exploratory analysis with the pulse of a detective story. Giving a portrait of the way a community chose to test itself on the threshold of new knowledge, Collins offers the rich sociological insight that can only be won from uncommon experience, from a long-standing dialogue with the community he studies, and from a moral engagement in the future of science.” —Richard Staley, author of Einstein’s Generation: The Origins of the Relativity Revolution In theory, at least, gravitational waves do exist. We are constantly bathed in gravitational radiation, which is generated when stars explode or collide and a portion of their mass becomes energy that ripples out like a disturbance on the surface of a serene pond. But unfortunately no gravitational wave has ever been directly detected even though the search has lasted more than forty years. As the leading chronicler of the search for gravitational waves, Harry Collins has been right there with the scientists since the start. The result of his unprecedented access to the front lines of physical science is Gravity’s Ghost, a thrilling chronicle of high-stakes research and cutting-edge discovery. Here, Collins reveals that scientific discovery and nondiscovery can turn on scientific traditions and rivalries, that ideal statistical analysis rests on impossible procedures and unattainable knowledge, and that fact in one place is baseless assumption in another. He also argues that sciences like gravitational wave detection, in exemplifying how the intractable is to be handled, can offer scientific leadership a moral beacon for the twenty-first century. In the end, Gravity’s Ghost shows that discoveries are the denouements of dramatic scientific mysteries. “A sociologist embedded (with full access!) in the LIGO Scientific Collaboration chronicles the search for gravitational waves. Though physicists, with very few exceptions, are in no doubt that gravitational waves exist, evidence for their passage through the new kilometer-length interferometers would nevertheless represent the scientific event of the twenty-first century. Harry Collins has turned the initial joined search exploiting the LIGO and Virgo instruments into a detective novel that exquisitely describes the social processes associated with discovery (and statistical analysis) in a large collaborative effort.”—Francis Halzen, University of Wisconsin–Madison and Director of Icecube Neutrino Detector Project

“In part an account of sociological fieldwork among scientists in the field and part astronomy-history mystery. . . . a terrific read.” —Nature Gravity’s Ghost and Big Dog brings to life science’s efforts to detect cosmic gravitational waves. These ripples in space-time are predicted by general relativity, and their discovery will not only demonstrate the truth of Einstein’s theories but also transform astronomy. Although no gravitational wave has ever been directly detected, the previous five years have been an exciting period in the field. Sociologist Harry Collins offers readers an unprecedented view of the research and explains what it means for an analyst to do work of this kind. Collins was embedded with the gravitational wave physicists as they confronted two possible discoveries—“Big Dog,” fully analyzed in this volume for the first time, and the “Equinox Event,” which was first chronicled by Collins in Gravity’s Ghost. Collins records the agonizing arguments that arose as the scientists worked out what they had seen and how to present it to the world, along the way demonstrating how even the most statistical of sciences rest on social and philosophical choices. Gravity’s Ghost and Big Dog draws on nearly fifty years of fieldwork observing scientists at the American Laser Interferometer Gravitational Wave Observatory and elsewhere around the world to offer an inspired commentary on the place of science in society today. “The physics junkie or philosophy of science enthusiast . . . will find lots to mull over.” —Science News “Makes for very entertaining reading.” —Daniel Kennefick, University of Arkansas, author of Traveling at the Speed of Thought
