These problems are intended to help staff and faculty improve their statistical computing (in R and other software) and analysis skills. Solutions should be e-mailed to
f.harrell@vanderbilt.edu, and later some solutions will be posted. Ideas for problems are welcomed.
Statisticians in the Department of Biostatistics get together, typically weekly, to work together on these problems. Once per month Dr Harrell joins the group to go over solutions.
