This Handbook contains thirty-one chapters by distinguished econometricians and statisticians from many countries. It is dedicated to the memory of Professor Viren K Srivastava, a profound and innovative contributor in the fields of econometrics and statistical inference. Viren Srivastava was most recently a Professor and Chairman in the Department of Statistics at Lucknow University, India. He had taught at Banaras Hindu University and had been a visiting professor or scholar at various universities, including Western Ontario, Concordia, Monash, Australian National, New South Wales, Canterbury, and Munich. During his distinguished career, he published more than 150 research papers in various areas of statistics and econometrics (a selected list is provided). His most influential contributions are in finite sample theory of structural models and improved methods of estimation in linear models. These contributions have provided a new direction not only in econometrics and statistics but also in other areas of applied sciences. Moreover, his work on seemingly unrelated regression models, particularly his book Seemingly Unrelated Regression Equations Models: Estimation and Inference, coauthored with David Giles (Marcel Dekker, Inc., 1987), has laid the foundation of much subsequent work in this area. Several topics included in this volume are directly or indirectly influenced by his work.
