## Fractional factorial designs 2^k-p

Some basic concepts about fractional experimental designs, as well as their generation and analysis in R. All other things being equal, the simplest explanation is usually the most likely. All code and data on this post are available on GitHub: Fractional Designs with R. What are fractional designs? These are designs in which a part or fraction of the treatments of a full factorial design are appropriately chosen, with the objective of determining which of the factors are significant using fewer experimental runs....
