This textbook offers a practice-oriented introduction to the methods of econometrics. Given the increasing importance of empirical analysis in both science and practice, the book aims to bring econometrics out of its formal-mathematical corner and make it accessible to a broader audience. In the design of the textbook, didactic considerations were prioritized over scientific elegance. Supported by numerous illustrations, detailed verbal explanations, and accompanying numerical examples, both the fundamental concepts of econometrics and more advanced topics are presented in an easily understandable manner. The textbook does not rely on matrix algebra. However, ambitious readers will find detailed matrix algebra representations of the material covered in the respective chapter appendices. The 7th edition.
