Case studies: global and diverse

Each of the 47 case studies begins with a real question and ends with an answer, based on real data and the methods taught in that chapter. For example:

  • Estimating gender and age differences in earnings (USA). More
  • Management quality, firm size and family ownership (Mexico, International). More
  • Predicting company default with machine learning (EU). More
  • Working from home and employee performance (China). More
  • Identifying successful football managers, and the effect of a change (UK). More

Endorsements

  • This exciting new text covers everything today's aspiring data scientist needs to know, managing to be comprehensive as well as accessible. Like a good confidence interval, the Gabors have got you almost completely covered!

    Joshua Angrist Professor of Economics, MIT · Nobel laureate

  • A beautiful integration of Econometrics and Data Science that provides a direct path from data collection and exploratory analysis to conventional regression modeling, then on to prediction and causal modeling. Exactly what is needed to equip the next generation of students.

    David Card UC Berkeley · Nobel laureate

  • This is an excellent book for students learning the art of modern data analytics. It combines the latest techniques with practical applications… For students looking to learn data analysis from one textbook this is a great way to proceed.

    Nicholas Bloom Professor, Stanford Economics & Graduate School of Business

  • I know of few books about data analysis and visualization that are as comprehensive, deep, practical, and current as this one; and I know of almost none that are as fun to read.

    Alberto Cairo Professor, University of Miami, School of Journalism

  • A rigorous textbook grounded in real-world learning, at once accessible and engaging to novice scholars and advanced practitioners alike. I have every confidence it will be valued by future generations.

    Kerwin K. Charles Dean, Yale School of Management

  • This is not an econometrics textbook, but a data analysis textbook. And a highly unusual one — written in plain English, based on simplified notation and full of case studies. An excellent starting point for future data analysts.

    Beata Javorcik Professor, University of Oxford; Chief Economist, EBRD

  • This is a fantastic book to have. Strong data skills are critical for modern business and economic research, and this text provides a thorough and practical guide to acquiring them. Highly recommended.

    John Van Reenen Professor, MIT Sloan & Department of Economics

  • This sophisticatedly simple book is ideal for undergraduate or Master's level Data Analytics courses with a broad audience. Using well-chosen case studies, they illustrate the techniques and discuss them patiently and thoroughly.

    Carter Hill Professor of Economics, Louisiana State University

  • In addition to the comprehensive treatment of modern econometric techniques, the book also covers the less glamorous but crucial aspects of procuring and cleaning data, and drawing useful inferences from less-than-perfect datasets.

    Laszlo Varro Chief Economist, International Energy Agency

  • Must purchase for anyone doing applied work… perfect for data scientists of all stripes.
