Designing DCE Choice Set Using R

The construction of experimental design is key to the successful implementation of DCE research. A full factorial design is the easiest design to create and use. It consists of all possible combinations of attribute levels, but it is often considered too costly and tedious for respondents. A recommended approach is to employ fractional factorial design in the DCE design, which uses a randomized but smaller combination of attribute levels. This chapter discusses techniques and steps to generate an orthogonal and balanced fractional factorial DCE design using R packages, such as package support.CEs.
