RESEARCH TRIANGLE PARK, N.C.—Rick Williams, Ph.D., a senior research statistician at RTI International, has been named an American Statistical Association Fellow.

Williams was named a Fellow for his outstanding contributions to statistical science in the development and application of analysis methods for correlated and sample survey data, in the development of RTI's statistical analysis software SUDAAN® and in the design of population surveys and observational studies.

Fellows are elected by their peers for outstanding contributions and leadership in statistical science. Given annually, the numbers of recipients are limited to no more than one-third of 1 percent of the ASA membership.

"This honor is a testament to Rick's significant contributions to the statistics field over many years," said John Heinrich, vice president, Health Sciences Division. "We are pleased to have someone of Rick's intellect and scientific stature on our team."

Williams joined RTI in 1977 where he routinely leads the statistical activities of large studies and often serves as overall project director. For more than 30 years he has made significant contributions to the development of SUDAAN and was its development leader for 5 years.

He has authored numerous research proposals, study reports, presentations and refereed articles in publications such as Biometrics, Lifetime Data Analysis and the Journal of the American Medical Association.

Williams frequently conducts workshops and training classes on the use of appropriate statistical analysis methods for cluster-correlated, longitudinal or repeated measures data, such as generalized estimating equations for marginal models, hierarchical linear and nonlinear mixed models and multilevel models.

Williams holds a doctorate in biostatistics from the University of North Carolina at Chapel Hill, a master's degree in statistics from Iowa State University and a bachelor's degree in mathematics from Arizona State University.
