A Simple, Practical, and Easy-to-understand Introduction to Econometrics Expanded econometric content includes new tests and procedures, such as the Breusch-Pagan test and the Weinstein-Prais Approach to Generalized Least Squares. Other expanded topics include the F-test, confidence intervals, the Language Multiplier test, and the Dickey-Fuller test. Notations and explanations have been simplified and clarified throughout, particularly in difficult topics like dynamic equations, dummy dependent variables, instrumental variables, and panel data. Pedagogical Features Help Students Grasp Core Concepts Economics Labs are innovative learning tools, located in the appendices, that give students hands-on opportunities to better understand economic principles both during and after class. Stata, the economic software package of choice among economists, is used throughout the text. All text examples and exercises are estimated with Stata, and an explanation of the software is included in the appendix and on the website. UPDATED! Answers to exercises in the text have been tripled and can be found in the appendices, allowing students to learn on their own. UPDATED! PowerPoint Slides throughout the text have been dramatically improved to replicate each chapter’s main equations and examples, as well as provide chapter summaries and key concept lists. UPDATED! The accompanying website is the text’s best version yet. It includes all of the text’s datasets in downloadable format, a guide to using Stata, improved PowerPoint slides, and answers to new econometrics labs.
