Description
Generate Optimal Row-Column Factorial Experiments.
Description
Provides tools for constructing row-column factorial experiment layouts for the estimation of main effects and two-factor interactions in factorial and fractional factorial experiments. The package implements generator-matrix based design construction methods motivated by 2fi-optimal row-column designs, where all main effects are estimable and as many two-factor interactions as possible are unconfounded; see Zhang, Pan and Shi (2025) <doi:10.1016/j.jspi.2024.106192>. It also includes theorem-based constructions, heuristic D-optimal search routines for unsupported or composite-level cases, utilities for building generator matrices, and diagnostic functions for evaluating aliasing and estimability properties of the generated designs.
