Over the recent years, the statistical programming language R has become an integral part of the curricula of econometrics classes we teach at the University of Duisburg-Essen. We regularly found that a large share of the students, especially in our introductory undergraduate econometrics courses, have not been exposed to any programming language before and thus have difficulties to engage with learning R on their own. With little background in statistics and econometrics, it is natural for beginners to have a hard time understanding the benefits of having R skills for learning and applying econometrics. These particularly include the ability to conduct, document and communicate empirical studies and having the facilities to program simulation studies which is helpful for, e.g., comprehending and validating theorems which usually are not easily grasped by mere brooding over formulas. Being applied economists and econometricians, all of the latter are capabilities we value and wish to share with our students.

Instead of confronting students with pure coding exercises and complementary classic literature like the book by Venables & Smith (2010), we figured it would be better to provide interactive learning material that blends R code with the contents of the well-received textbook Introduction to Econometrics by J. Stock & Watson (2015) which serves as a basis for the lecture. This material is gathered in the present book Introduction to Econometrics with R, an empirical companion to J. Stock & Watson (2015). It is an interactive script in the style of a reproducible research report and enables students not only to learn how results of case studies can be replicated with R but also strengthens their ability in using the newly acquired skills in other empirical applications.

Conventions Used in this Book

  • Italic text indicates new terms, names, buttons and alike.

  • Constant width text is generally used in paragraphs to refer to R code. This includes commands, variables, functions, data types, databases and file names.

  • Constant width text on gray background indicates R code that can be typed literally by you. It may appear in paragraphs for better distinguishability among executable and non-executable code statements but it will mostly be encountered in shape of large blocks of R code. These blocks are referred to as code chunks.
