Small Three-Level Second-Order Designs With Orthogonal Blocks

  • Aloke DeyEmail author

Using suitable incomplete block designs with block size three, orthogonally blocked three-level second-order designs are proposed. These designs have reasonably high D-efficiencies and are often much smaller than the existing designs, in terms of block size and/or the total number of points.
