March 11, 2019 (Kitchener, Ontario) – SigmaXL Inc., a leading provider of user-friendly Excel Add-ins for Statistical and Graphical analysis, announces the release of SigmaXL Version 8.1.

“SigmaXL was designed from the ground up to be a cost-effective, powerful, but easy to use tool that enables users to measure, analyze, improve and control their service, transactional, and manufacturing processes. As an add-in to the already familiar Microsoft Excel, SigmaXL is ideal for Lean Six Sigma training or use in a college statistics course. Version 8.1 adds Taguchi Design of Experiments (DOE) Templates,” said John Noguera, CTO, SigmaXL.

Features of the Taguchi DOE Templates include:

  • Taguchi Orthogonal Arrays include:
    • 2 Level: L4, L8, L12, L16
    • 3 Level: L9, L27
    • Mixed 2/3 Level: L18
  • Available Signal-to-Noise Ratios:
    • Nominal is Best
    • Nominal is Best (Variance Only)
    • Nominal is Best (Mean Square Deviation with Target)
    • Larger is Better
    • Smaller is Better
  • Fill in the blanks template, charts automatically update
  • Levels are discrete categorical so may be numeric or text
  • Predicted Response Calculator and Charts for Mean, Standard Deviation (or Ln Standard Deviation) and Signal-to-Noise Ratio
  • Up to 27 Replications for Outer Array (i.e., support up to L27 Outer Array)
  • Pareto of Deltas (Effects) and ANOVA SS (Sum-of-Squares) % Contribution (for Main Effects and Two-Way Interactions)
  • Main Effects Plot and Interaction Plots (if applicable)
  • For designs with aliased interactions, a drop-down list of available aliased interactions is provided. This is much easier to use than Linear Graphs.
  • Column assignments to Orthogonal Array are optimized to ensure maximum design resolution.

Dr. Ranjit K. Roy, Consultant and Author of the book A Primer On The Taguchi Method: “The newer capabilities you introduced in the Taguchi Templates of SigmaXL are very useful. The common experiment design options you now offer (Templates on use of L-4, L-8, …, L-27 orthogonal arrays), are quite pragmatic and user-friendly. Most application minded practitioners should find these templates very attractive for their experimental designs and analyses tasks. Users can now easily design a Taguchi experiment using a selected template and carry out the trial conditions. Once the test results are entered, analyses are performed instantly, saving valuable time for interpretation of experimental outcomes.”
