Stephen Pollock, Econometric Theory "I continued to be pleasantly surprised by the variety and usefulness of its contents" Isabella Verdinelli, Journal of the American Statistical Association Continuing the success of their first edition, Magnus and Neudecker present an exhaustive and self-contained revised text on matrix theory and matrix differential calculus. Matrix calculus has become an essential tool for quantitative methods in a large number of applications, ranging from social and behavioural sciences to econometrics. While the structure and successful elements of the first edition remain, this revised and updated edition contains many new examples and exercises.Contains the essentials of multivariable calculus with an emphasis on the use of differentialsMany new examples and exercisesFulfils the need for a unified and self-contained treatment of matrix differential calculusIncludes new developments in this fieldPart I presents a concise, yet thorough overview of matrix algebra, while the second part develops the theory of differentials. The remaining Parts III to VI combine the theory and application of matrix differential calculus providing the practitioner and researcher with both a quick review and a detailed reference.
