Build 1.0.7

  • Fixed a case where Lenth's PSE could be incorrect if a large number of effects were removed from the model.
  • The surface plot now allows precision 0 along the Z-axis.
  • Resolved an issue where altering the data type of a Reliability DOE could corrupt the design.

Build 1.0.6

  • General Level designs created through the "Add From File…" functionality are now capped at 10 factors.
  • Updated the 2 Level Fractional Factorial Design example.
  • Updated the Motor Life Test example.
  • Added reference to the theory help file.

Build 1.0.5

  • When importing a General Level Factor design, effect terms are now limited to 2-way interactions for very large designs.
  • The Contour/Surface plot now allows an Axis Math Precision value of 0.

Build 1.0.4

  • Updated training guide examples.

Build 1.0.3

  • Resolved an issue with saving projects when certain Windows printer drivers are present on a user's system.
  • Reliability DOE data can now be transferred to Weibull++ 7.5 or ALTA 7.5 for further analysis.
  • The design can now be sorted by any number of factors. This functionality is accessed from the Sheet menu (Sheet -> Sort -> Sort By Factors).
  • If the response contains a calculated Prediction sheet, the Prediction can be added to a report through the Report Generator.
  • Responses from a Multiple Linear Regression can now be selected for use in Side-by-Side plots.
  • The Contour/Surface plot now has a more intuitive Plot Setup to easily modify the plot settings.

Build 1.0.2

  • Added language support for Japanese.
  • Added an Analysis History feature in order to store and view the settings and results for each calculation performed on a design.
  • Added the ability to modify the design after it has been created by adding replicates, adding center points, folding the design, or adding an axial block.
  • Added a Report Generator to build your own report by selecting which items to add to a report spreadsheet.
  • Added the ability to import designs from Excel or text files using the "Add From File..." command.
  • Added the ability to select the number of factors and the column index used for each factor in Taguchi OA designs.
  • Added an option to use "repeated measurements" in factorial and response surface method designs in order to analyze mean and variance in a single response.
  • Added support for quantitative factors in general full factorial and Taguchi OA design types.
  • Added Term Effect plot to compare the effects of any terms included in the model.
  • Added Residual Autocorrelation plot.
  • Added Residual Histogram to one factor designs.
  • Added Anderson-Darling test results to the Residual Probability plot.
  • Added Scatter plots to all multi-factor designs.
  • Added Lenth's method to the Regression Information in order to determine the significant effects when there is no error in the model.
  • Added the Y Min and Y Max information to the Transformation window.
  • Added the ability to name block values and increase the number of blocks in the design after it has been created.
  • Added "Available Designs" information for all design types in the Design Wizard.
  • Added the ability to specify the block value used when calculating fitted means using custom values in most effects plots.
  • Added labels to the lines in the Interactions plot to improve readability when it is printed.
  • Added the PRESS and R-sq(pred) information to the Analysis sheet in response surface method designs.
  • Added the ability to select significant effects in the Select Effects window.
  • Resolved issues when the factor levels or block levels varied between responses due to missing data.
  • Resolved issues with the actual equation displayed in the Analysis Summary. Now the full actual equation is displayed.
  • Removed the Main Effects plots from the Interaction Matrix.
  • Cleaned up the display of the results in the Analysis sheet to aid readability.
  • Moved the initial alias structure to a separate page of the Design Summary.
  • Added the ability to specify negative factor and block generators in factorial designs.
  • Added an option to Alter Data Type of Reliability DOE designs after they have been created.
  • Added two new examples, "Motor Life Test", a Reliability DOE example, and "Paint Example", a Taguchi Robust design.
  • Updated example files.
  • Updated training guide files.
  • Updated online help file.
