WebMay 1, 2024 · To know whether or not the ϕ-optimal designs generated by Algorithm 1 can also be obtained by conventional software, the R function optFederov in the package AlgDesign developed by Wheeler (2024), which is an implementation of the exchange algorithm proposed by Fedorov (1972), is used to generate competing designs. WebStep 1: The function gen.factorial( )included in the AlgDe- sign package (Wheeler 2004a) is used for creating a full factorial design. Step 2: The function optFederov( )included in the AlgDesign package (Wheeler 2004b) is used for generating a frac- tional factorial design ((mixed) orthogonal array) from the full factorial design.
