Full Changelog

13.0.5 released May 10, 2021

  • Fixed multithreading bug that was causing combined optimal builds to run extremely slow.

  • Fixed a bug where discrete factor data were changed after cancelling an augment.

  • Upgraded to RLM 14.1.

  • When changing a font preference the previous font type will be pre-selected.

  • Turning on/off the legend now works correctly on the Pareto plot.

13.0.4 released April 14, 2021

  • Added One Factor RSM tutorial that covers Propagation of Error and Optimization. Updated the remaining tutorials.

  • The dex_activate.exe utility will now copy over custom ports from the previous license to the new one.

  • Fixed display error in the factor tool where the input box appeared in the corner.

  • Changing the name of a response will now change the corresponding analysis name, if the analysis name has not already been modified.

  • Fixed a bug causing missing intervals in some combined analyses.

  • High/Low labels on the interaction plot are now draggable.

  • Tick mark labels on axes with two mixture components no longer overlap.

  • Using the Import Data tool with categorical data now consistently codes the levels in the order they appear.

  • The default model for split-plot analyses is now the model that the design was built for.

  • When adding a new analysis the dropdown will default to the response that is currently selected.

  • In some graphs the flags could not be expanded. This has been fixed.

  • In the optimization, when changing from an analysis with a transform to one without, the criteria settings are preserved.

13.0.3 released March 3, 2021

  • Fixed simulation equation errors when using a non-US locale.

  • Added analysis name to several reports to distinguish between multiple analyses.

  • Fixed some multiple-selection and pasting issues in Windows.

  • Fixed a crash when selecting an empty response from the Evaluation dropdown.

  • Fixed a bug that caused some valid rows to be ignored when leaving the Design Layout.

  • Fixed an indexing error that would cause p-values to be out of order in the Coefficients Table.

  • New runs added via the Modify Design Space augment will now go into a new block.

  • Added missing labels back to interaction plot when the legend is off.

  • Flags can now be expanded when showing all responses in the Numerical Optimization graphs.

  • Labels on the Pareto chart now have backgrounds, and can be clicked to bring to the forefront if they are overlapping.

13.0.2 released January 25, 2021

  • Support for Big Sur.

  • Improved visibility in data tables when using a dark background (e.g. macOS Dark Mode).

  • Deleting observations in the Confirmation node now deletes the correct row.

  • Fixed a crash when using ctrl+z to undo a duplication of more than 50% of rows.

13.0.1 released January 5, 2021

  • Using the arrow keys after typing in a cell will now move to an adjacent cell, similar to the behavior of other popular spreadsheet software.

  • Removed KCV order for double mixture designs.

  • Fixed several crashes related to deleting analyses.

  • When columns are rearranged after using Import Data the names are correctly reassigned.

  • If factor levels are missing when using Import Data, the runs are now ignored.

  • When the number of blocks changes due to an augment of a design, the block column is automatically shown.

  • Treatment means no longer show INF Std. Error for a mean model, instead they are blank.

  • Fixed a crash when clicking on Graph Columns for certain designs.

  • Fixed an issue with the Y axis changing when the legend is undocked on a histogram.

  • Importing Data now does a better job of displaying floating point numbers.

  • Fixed several crashes when using Import Data and the columns are in non-standard order.

13.0.0 released December 21, 2020

Poisson Regression

  • Responses with count data can be analyzed with Poisson Regression.

Design

  • A design space augment wizard is available to expand an existing design.

  • Editable constraints in the constraint node.

  • Runs that are outside the constraints are flagged, but can still be used in the analysis.

  • Runs that are outside the constraints can be moved back in to valid space via the right-click menu.

  • Importing data is much easier using the Import Data Set option. You just have to paste in your data.

  • A ribbon has been added to the Design Layout screen for easy access to several features.

  • You can now round factor values by right-clicking the column header.

  • Adding verification runs after an analysis has been performed will no longer invalidate the analysis.

  • Continuous and discrete numeric factors are now indicated in the Design Summary.

Analysis

  • You can now create multiple analyses for a single response.

  • When copying equations to Excel, the response name is now included.

  • Pearson, Deviance, and Hosmer-Lemeshow goodness-of-fit tests are available for logistic regression.

Diagnostics

  • There is a new preference for the default layout of the Diagnostics tabs.

Graphs

  • Control multiple graphs at the same time with the factors tool.

  • There is a Box and Whiskers plot available in the Graph Columns node.

  • Perturbation and Trace plots are now colored by factor.

  • A new option in All Factor graphs will only show factors that are used in the model.

  • If there are a large number of ticks on a graph only a subset will be shown.

  • For large designs the Leverage graph is scaled to the maximum value, rather than 1.0.

  • When the crosshair on an FDS graph is above 80% it changes to black, rather than red.
