Click the button below to access SigmaXL's Virtual Menu:



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 10 adds new tool selection guides, XYZ Contour/Surface Plots, General Linear Model, new MSA templates, and more! Click here to view the features available in SigmaXL!

    • General Linear Model. Extends Advanced Multiple Regression to include:
      • Fixed and Random Factors
      • Nested Factors
      • Covariates (can be Nested)
      • For Random or Mixed Random/Fixed Factors with a balanced design, the ANOVA and Variance Components (VC) report is given based on Expected Mean Squares. VC confidence intervals using Restricted Maximum Likelihood (REML) are included.
      • If the design is unbalanced or model is non-hierarchical, REML is used to compute the VC values and confidence intervals. Fixed Effects Tests are based on Satterthwaite approximation degrees of freedom.
      • Main Effects with Confidence Intervals and Interaction Plots of Fitted Means for Non-Nested Fixed Factors
      • Tukey and Fisher Pairwise Comparison of Means for Non-Nested Fixed Factors
      • Predicted Response Calculator
      • Multiple Response Optimization for Nested or Non-Nested Fixed Factors
