ADX Interface for Design of Experiments

The SAS ADX Interface for Design of Experiments includes enhancements related to response surface designs, mixture designs, general factorial designs, and split-plot designs. Furthermore, ADX can now import data from SAS data sets or external file formats, and it can export design information to SAS data sets or external file formats.

The SAS 9.2 ADX Interface now enables you to do the following:

• create general factorial designs with factors having up to nine levels

• construct and analyze two-level full factorial and fractional factorial split-plot designs

• choose a mixed-level design from a new expanded design selection

• analyze unstructured experimental data that is imported from external sources

• analyze fitted models by using the new graphical ANOVA

• construct a lambda plot to evaluate the need for a response transformation

• add center points to a design before or after replication

• add replicated points in a new block

• apply a user-specified alpha value for the graphical techniques that are used to fit and optimize a model

• delete inactive factors and project a fractional-factorial design to a higher-resolution design

• join the means in a box plot

• show clear and aliased effects in the alias structure

• display confidence intervals in the response calculator and experiment report

• honor block structure in a blocked design during design randomization

The ADX interface is documented in Getting Started with the SAS 9.2 ADX Interface for Design of Experiments.
