Econometrics

This textbook offers an applied introduction to the methods of econometrics. Given the increasing importance of empirical analysis in science and the professional world, the book aims to move econometrics beyond its formal mathematical corner and make it accessible to a broader audience. In developing the textbook, the didactic profile was therefore given priority over scientific elegance. Supported by numerous illustrations, detailed verbal explanations, and accompanying numerical examples, both the fundamentals of econometric and more demanding topics are presented in an easily understandable way. The main sections of the Chapters do not use matrix algebra. However, in each chapter's appendix, ambitious readers will find detailed matrix-algebra-based representations of the material covered in the main sections.

Presents intuitive explanations and many graphical illustrations Discusses that matrix algebra is not required Provides numerous empirical examples from various fields
