This book is designed to fill the gap between introductory undergraduate texts and advanced texts for graduate students. Its comprehensive coverage ensures that readers understand both the 'how' and the 'why' of econometrics, as it explains not only the mathematical techniques for econometric problem-solving but also the mathematical foundations of the discipline. Developed with careful pedagogical methodology throughout, the text makes full use of empirical examples and includes appendices providing 'ready reference' and refresher courses on basic mathematics, as well as further material for the more advanced student.
