Toronto (July 27, 2009) – SigmaXL, a leading provider of user friendly Excel Add-ins for Statistical and Graphical analysis, announces the release of SigmaXL Version 6. New features include:

  • Powerful Excel Workbook/Worksheet Manager
  • Lean Value Stream Mapping Template

  • Distribution Fitting Report

An example of SigmaXL’s power and user friendliness is in the new Process Capability for Nonnormal data. Box-Cox transformations can be applied to data with negative values. SigmaXL considers Box-Cox and Johnson transformations along with 16 nonnormal distributions and automatically selects the best fit. A distribution fitting report displays the results graphically with histograms, curve fit and probability plots sorted by best fit. “This enables practitioners to easily deal with their real world data,” said John Noguera, CTO, SigmaXL.

SigmaXL is rapidly becoming the tool of choice for Lean Six Sigma practitioners and business professionals around the world. As an add-in to the already familiar Microsoft Excel, SigmaXL is ideal for training or use in a college statistics course.

A free 30-day trial version is available for download from the SigmaXL website at:
