gen.PBCD: Plackett-Burman Composite Designs (Draper and Lin's Method)

Description

Generate Plackett-Burman composite designs proposed by Draper and Lin (1990) for k = 3 to 7

Usage

gen.PBCD(k, alpha ="rotatable", n.center = 0)

Arguments

k

The number of factors or independent variables, k = 3 to 7.

alpha

Axial distance. User may specify "rotatanble", "face-center", or other numeric numbers. See examples.

n.center

The number of center points

Value

• gen.PBCD is called to generate the data frame of the design matrix of the PBCD
