Experimental Designs

Matrex provides a very wide range of designs, including the following:

• 2-Level Full Factorial
• 2-Level Fractional Factorial
• Multi-Level Factorial (including D-Optimal)
• Plackett-Burman 
• Fold-Over 
• Central-Composite
• Face-Centred Cubic
• Box-Behnken 
• Augmented (including D-Optimal)
• Blocked (including D-Optimal)
• Mixture (including D-Optimal and Extreme Vertices)
• Taguchi Orthogonal Arrays

Special Design Functions

Matrex provides special design functions designed to allow the experimenter to use a sequential experimentation strategy.  These are:

• Augmented fractional factorial designs (using D-Optimality)

• Augment resolution-V 2-level factorial to central-composite

By using sequential experimentation, you can build on knowledge gained at each step, allowing you to refine your design and improve your model.

Analysis Options

Included in the analysis options are the following:

• Contrasts/Effects

• Multiple Regression model-building

• Analysis of Variance

• ANOM (Analysis of Means)

Plotting Options

The following plotting options are available:

• Effect plots

• Interaction plots

• Scree plots

• Normal plots 

• Residual plots

• Surface plots

• Lenth plots
