Introduction to Econometrics provides students with a simple mathematics notation and step-by step explanations of mathematical proofs to facilitate a thorough understanding of the subject. Extensive exercises throughout encourage students to apply the techniques, thus gaining confidence in what they have learnt. A complete teaching and learning package, this text is accompanied by an Online Resource Centre featuring resources for lectures and students such as a student guide, PowerPoint slides, instructors manual, additional exercises, and links to cross-section and time series data sets. To reflect the student-friendly approach, the text design has been made even easier for students to learn from and the text is now in two colour. There is also a new chapter on Panel Data.
