Overview of ADX

Design Objectives

Designs offered by ADX can be used to achieve specific experimental objectives, as shown in Table 2.1.

Table 2.1: Design Types and Their Objectives

Design Type	Model Objective
Two-level screening	Identify factors of greatest impact on response
Response surface	Model curvature effects
Mixture	Model effects that are components of a blend
Mixed level	Model with two- and three-level, mixed quantitative and qualitative factors
Optimal	Model with D- and A-optimal designs for irregular design regions
Split-plot	Model effects where some levels are hard to change
General factorial	Model with full factorial designs and factors with several levels
