SCCDdesign: Construction of Screening Designs for Mixed Level Continuous and
Categorical Factors
Constructs screening designs for experiments involving
continuous and categorical factors with multiple levels. The package
implements methods for constructing mixed-level screening designs,
involving factors with more than two levels. It also evaluates the
statistical performance of screening designs throughdev power to identify
active effects and Type I error rates.
The package implements three methods proposed by Jones, B.,
Lekivetz, R., Majumdar, D. and Nachtsheim, C. (2025)
<doi:10.1080/00401706.2024.2362149> for generating efficient
screening designs involving three-level continuous and two-level
categorical factors for even run sizes.
It also includes Paley Type I and Type II constructions for conference matrices
and pseudo conference matrices obtained using the coordinate exchange algorithm by Jones, B. and Nachtsheim, C. J. (2011)
<doi:10.1080/00224065.2011.11917841> which are used
in the development of these screening designs.
