Menu.ccdTab1: Basic information for Central Composite Designs

Description

Basic information for Central Composite designs

Brief statistical background

Central composite designs can have three (alpha=1) or five levels in all factors and are useful for fitting second order polynomials to experimental data based on several quantitative response variables. They can be used in a process of sequential experimentation, experimenting first with the cube portion and later adding (a) star block(s). For more information, look at the help file for function ccd.design from package DoE.wrapper or at ccd from package rsm.
