The book "Econometrics: Theory and Practice" presents the basic theory of Econometrics with examples, solved exercises, and econometric problems to solve in each chapter. Its purpose is initially to help the reader understand the basic concepts and assumptions needed before modeling and testing economic theories. Then, systematically use the appropriate econometric methods to identify any problems in various research needs. Finally, solve these problems in order to evaluate and propose appropriate policies and provide the ability to make reliable forecasts.

As Econometrics is based on the synthesis of Economics, Mathematics, and Statistics, the theoretical foundation is established by understanding the necessary background knowledge of Statistics and Mathematics. This basic knowledge is necessary for the proper and complete learning of the basic principles governing Econometrics.
