Biography

A. Clifford Cohen is Professor Emeritus of Statistics at the University of Georgia in Athens, where he has been affiliated since 1947. An editorial board member of the Journal of Quality Technology, Dr. Cohen has published more than 60 research papers and technical reports on the subjects of estimation from truncated and censored samples, and modified estimators. He is a Fellow and Founding Member of the American Society for Quality Control, Founding  Member of the Operations Research Society of America, Fellow of the American Statistical Association and American Association for the Advancement of Science, and member of the Institute of Mathematical Statistics, Mathematical Association of America, International Statistical Institute, and Sigma Xi. He is certified by the American Society for Quality Control as both a quality engineer and a reliability engineer. Dr. Cohen received the B.S. (1932) and M.S. (1933) degrees in electrical engineering from Auburn University in Alabama, and M.A. (1940) and Ph.D. (1941) degrees in mathematics from the University of Michigan in Ann Arbor. Betty Jones Whitten is Associate Professor in the Department of Management Sciences at the University of Georgia in Athens. She has coedited one book, and authored or coauthored more than 30 articles, proceedings papers and technical reports on her research interests in estimation procedures in life testing distributions, modified moment estimation for the three-parameter gamma, inverse Gaussian, lognormal and Weibull distributions, and other related topics. She is the recipient of the first Josiah Meigs Award for Excellence in Teaching and Pro Optime Perdocendo Honoratus Award from the University of Georgia. Dr. Whitten is treasurer of the Decision Sciences Institute (national office), president of the Southeastern  Region of the Decision Sciences Institute, and a member of the American Statistical Association, Sigma Xi, Phi Kappa Phi, and Beta Gamma Sigma. She received the B.S. (1962) and M.S. (1963) degrees in mathematics from the University of Illinois in Urbana, and Ph.D. (1972) degree in statistics from the University of Georgia.
