All Products: Spanish Translation

The user interface for all the version 8.0 add-ins in the DecisionTools Suite have been translated into Spanish.

While the user interface and example files have all be localized into Spanish, unfortunately the Spanish product documentation was not completed as of the release date. Only the Evolver, PrecisionTree, and NeuralTools documentation is available in this release. If you are using @RISK’s online help system, the product will automatically start delivering Spanish documentation content as soon as it becomes available. If you are using the local help system of @RISK or the other products, you will need to update your software to get the translated documentation.

@RISK: Disable All Correlations During Simulations

There is a new Simulation Setting on the Sampling Tab (Figure 1, below) to disable all the correlations defined in your model. A shortcut for this setting can also be found in the Correlation Menu (Figure 2, below).

@RISK: Identify and Graph Outliers in Box Plots

Box Plots on the Summary Window or Data Viewer Window can now display outliers. This can be customized for an individual graph from the Graph Options dialog, or for all graphs from within @RISK’s Graphing Preferences dialog.

@RISK: Calculate Joint Probabilities Using New Statistic Functions

Two new @RISK statistic formulas allow you to calculate joint probabilities for two or more simulated input or outputs.

  • RiskJointProb2Dim calculates the fraction of iterations where a two simulated outputs or inputs fall in a given quadrant. (This matches the results shown by the delimiters in an @RISK scatter graph.)

  • RiskJointProbMultiDim calculates the fraction of iterations where any number of outputs or inputs meet a given set of range conditions.

@RISK: Select Report Outputs and Inputs across Multiple Worksheets

This new feature allows you to select multiple Excel ranges from different worksheets in the same workbook (Figure 3, below). You can also delete specific ranges, or change the order of how they will be displayed in your report.

@RISK: Choose and Order Results in Summary Graphs

The Summary Trend and Box Plot graphs now have a Summary Graph Manager that allows you to add, remove, and order the inputs and outputs shown in the graph. You can find it in the Settings/Actions menu of the Summary Graph Window.

@RISK: Model List Status Column Helps Identify Locked Inputs

The Model List Window (Figure 4, below) and Results Summary Window (Figure 5, below) now include a status column to visually show when an input is locked. From the Model List, you can lock and unlock inputs from the Edit menu or right-click context menu.

Figure 5 - Results Summary with Locked Inputs

@RISK: Configure Two-Color Tornados

The Change in Output Statistic Tornado now allows the customization the two colors of the bars, so you can better differentiate between high and low inputs. The colors can be controlled for an individual graph using the Graph Options dialog. To control the colors for all new graphs, go to the Graphing Preferences dialog.

RiskOptimizer Graph to Compare Original vs Optimized Distribution

The Browse Results Window now allows you to compare the original distribution to the optimized distribution found by RISKOptimizer.

@RISK: New Dynamic Welcome Screen Content

Find the latest news from Palisade and @RISK in the new dynamic Welcome Screen. If you prefer to disable the Welcome Screen at startup, we’ll put notifications on the @RISK menu whenever there is new content available.

@RISK: Increased Report Limits

Summary and Detailed Statistics report tables can now include up to 500 inputs or outputs.

@RISK: New Goal Seek User Interface

The @RISK Goal Seek feature has been updated with an improved user interface and experience.

@RISK: Better Display Scaling

This version of @RISK has improved handling of different display scales (also known as DPI scales) in its windows, graphs, and reports.

@RISK: Add Property Functions from the Insert Menu

The ability to add Property Functions to your @RISK functions using the Insert Menu has been restored to @RISK version 8.

@RISK: Reference Overlays on Non-Active Sheets in the Define Distribution Window.

The option to overlay a distribution from an Excel range in the Define Distribution Window now supports selecting Excel cells from a non-active sheet.

NeuralTools: New Classification Performance Measures Report

For binary classification problems, one of the values in the dependent variable can now be defined as the “Positive Category”. With this designation we can present the testing results in terms of True/False Positives or Negatives; as well as reporting Accuracy, Precision, Recall, and F1 Score for the neural net’s performance.

Release 8.0.1 - July, 2020


All Products: Dynamic Array Support

Some versions of Office 365 now include support for a new type of array formulas known as “dynamic arrays”. This resulted in changes to the syntax of some other non-array formulas: users will notice the “@” sign in some formulas, where it did not appear before. While TopRank itself does not make use of dynamic arrays, it has its own custom cell functions, and their syntax was affected by the introduction of dynamic arrays. This version has been made compatible with the new syntax.

PrecisionTree: Link to BigPicture Removed

The BigPicture add-in has been discontinued. The “View in BigPicture” ribbon command has been removed in this version.

TopRank: Running TopRank and @RISK at the Same Time

Previous versions of TopRank would sometimes require special reconfiguration of @RISK so the two add-ins could both be loaded at the same time. This requirement has been removed in this version.
