Welcome to the Working Papers site for the Department of Biostatistics at the University of Michigan. The papers available on this site represent a selection of the current research being conducted by members of our department, which includes 23 faculty, 31 staff and 120 students. The Department of Biostatistics plays an instrumental role in bringing biostatistical expertise to a wide spectrum of health-related problems. We seek to advance knowledge in biostatistics and health through educational programs for students and applied researchers. The Department also plays a major service role, both within the University of Michigan and on the national and international stage. Read more...
