    Careful selection of an experimental design for a bioassay substantially improves the precision of effective dose (ED) estimates. Design considerations typically include determination of sample size, dose selection, and allocation of subjects to doses. DOSESCREEN is a computer program written to help investigators select an efficient design for the estimation of an arbitrary ED. This report establishes the statistical basis for DOSESCREEN and suggests several ways to utilize DOSESCREEN out-put. A copy of the computer program in Fortran 77 is provided so users can easily convert DOSESCREEN to their own computer system.
