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

In VdgRsm: Plots of Scaled Prediction Variances for Response Surface Designs

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 "rotatable", "face-center", or other numeric numbers. See examples.
n.center	The number of center points

Value

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