Full Changelog

Fixed several issues with Python scripts crashing or timing out if many designs are opened in one session.

Fixed an issue where constraints entered as a ratio did not display the correct intercept in the constraints interface.

Optimal builds with more Lack of Fit points than eligible candidates will now finish building with the maximum number of Lack of Fit points possible.

Commas no longer appear in discrete factor levels in the Factor Info dialog.

The equation input now correctly recognizes implicit multiplication when a factor identifier is next to a parenthesis.

The limit on the number of factors in Custom Optimal designs has been increased to 75.

The Coefficients Table has additional options for hiding blank terms and other formatting options.

Changing the preferences for categoric level colors now overwrites the color settings in the Factor Info dialog.

Fixed a crash when using Import Data with an empty Block column.

Fixed an issue causing Contour plots to draw very slowly.

Exporting the Alias Matrix to PowerPoint now works correctly.

Fixed a crash building an optimal design with multiple numeric and categoric factors.

Durbin-Watson Statistic - Added the Durbin-Watson statistic to the diagnostics. This is a measure of auto-correlation in the residuals.

Fixed unhandled exception when editing the constraints.

Removed bold lines that appear when transposing tables in the Point Prediction report.

Fixed a crash in Numerical Optimization when a categorical factor is present.

Fixed a crash when using the Excel import feature with a file that is not an Excel file.

Adding a new graph via the + button in Custom Graphs now works consistently.

Fixed a crash in the analysis of Equation-Only responses.

Rebuilding a design with discrete factors no longer warns about unique numeric values.

The Ramps view in Numerical Optimization now shows the solution correctly when the Logit transform is applied.

Gaussian Process Models for Noisy Responses - Gaussian Process models are now available for responses with noise. Stat-Ease 360 only.

Lifetime Analysis with Weibull (Python) - A Python script that can perform lifetime analysis with a Weibull fit is available in the Script dialog. Stat-Ease 360 only.

Transpose Tables - Most tables in the software can now be transposed by right-clicking on the top-left header cell.

Analysis Summary - Added Lack of Fit and Curvature p-values to the Analysis Summary table.

Excel Import/Export - You can now import from, and export to, Excel files in Design-Expert. Previously was Stat-Ease 360 only.
