A family of orthogonal main effects screening designs for mixed-level factors

B Jones, R Lekivetz, C Nachtsheim - Journal of Quality Technology, 2023 - Taylor & Francis
There is limited literature on screening when some factors are at three levels and others are
at two levels. This topic has seen renewed interest of late following the introduction of the …
