Introductory Econometrics: A Modern Approach
Econometrics has moved from a specialized mathematical description of economics to an applied interpretation based on empirical research techniques - and the modern approach of this innovative book is proof. Introductory Econometrics bridges the gap between the mechanics of econometrics and modern applications of econometrics by employing a systematic approach motivated by the major problems currently facing applied researchers. Offering a solid foundation for social science research, the book provides important knowledge used for empirical work and carrying out research projects in a variety of fields.
