gen.HSCD: Hartley's Small Composite Designs (HSCDs)

Description

Generate Hartley's small composite designs for k = 2 to 7

Usage

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

Arguments

k

The number of factors or independent variables, k = 2, 3, 4, 5, 6, and 7.

alpha

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