• General (multilevel) factorials for categorical factors
• Up to 256-run, two-level designs with optimum blocking options
• Taguchi orthogonal arrays
• Power calculations included in the sophisticated design evaluation tools.

• Ignore a row of data while preserving the numbers
• Add new factors and blocking to existing designs
• Change factors from numerical to categorical and back
• Define your own generators for fractional factorial designs
• Select terms for model, error or to be ignored (allows analysis of split-plot or nested designs)
• Take advantage of many new user preferences, for example: change the significance threshold to 0.01 or 0.1 "p-value" (default is 0.05).

• Greatly expanded context-sensitive help
• Better guidance for choice of model
• Annotated views to provide explanation of statistical outputs.

• Prior to viewing the ANOVA for two-level fractional factorials, a warning pops up that model is aliased, and the opportunity is provided to substitute aliased effects
• F-tests on individual model terms
• Confidence intervals on coefficients.

• Predicted versus actual with a 45 degree line
• Box-Cox plot for choosing the best response transformation

• Standard toolbar added for save, print, etc.
• 32-bit architecture for maximum performance on Win 9x, NT and beyond
• Ability to export any grid view as ASCII text, for example: the design layout.
