title: 'MixFrac: Fractional Factorial Designs with Alias and Trend-Free Analysis'
version: '1.0'
doi: 10.32614/CRAN.package.MixFrac
abstract: Constructs mixed-level and regular fractional factorial designs using coordinate-exchange
  optimization and automatic generator search. Design quality is evaluated with J2
  and balance (H-hat) criteria, alias structures are computed via correlation-based
  chaining, and deterministic trend-free run orders can be produced following Coster
  (1993) <https://doi.org/10.1214/aos/1176349410>. Mixed-level design construction
  follows the NONBPA approach of Pantoja-Pacheco et al. (2021) <https://doi.org/10.3390/math9131455>.
  Regular fraction identification follows Guo, Simpson and Pignatiello (2007) <https://doi.org/10.1080/00224065.2007.11917691>.
  Alias structure computation follows Rios-Lira et al.(2021) <https://doi.org/10.3390/math9233053>.
