What's New in Version 6

• Additional experimental designs (and capability for analysis)
  • General (multilevel) factorials for categorical factors
  • Up to 256-run, two-level design
  • Power calculations included in the sophisticated design evaluation tools.

• More flexibility
  • 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).

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

• Changes to analysis of variance (ANOVA) output
  • 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.

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

• Improved interface
  • 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.
