Most textbooks of econometrics either are too advanced for the majority of students or achieve simplicity by omitting many essential topics. In this book the author has simplified the mathematical presentation of the econometric models while providing a comprehensive treatment of the subject.The text is divided into three parts. Part 1 begins with a brief discussion of the procedure that must be followed in any applied econometric research. It then examines the theory of correlation and the simple linear regression model, and develops the method of analysis of variance and its use with regression analysis. Part 2 is devoted to the assumptions of the linear regression model, their implications for the values of the parameters of the economics relations, their tests and the corrrective action to take when they are violated. Part 3 deals with models of simultaneous relationships.The appendix includes examples and questions relating to economic applications. BUY IT, STUDY IT AND THE ECONOMY ROBUST!
