Generating efficient designs for comparative experiments using the SAS procedure OPTEX

摘要

Good agricultural experiments require efficient experimental designs, so availability of convenient software for design generation is important. Here, we consider the SAS procedure OPTEX, which was developed as a general-purpose design generation tool focused mainly on response surface regression experiments. This procedure can also be used to generate good designs for comparative experiments as needed in crop science research. This is illustrated here for the most commonly used experimental designs.
