Compute a specified statistic for slots in an ensemble data set. For more information on Ensemble Data Sets, see Ensemble Data Tool in Solution Approaches. Statistics are computed for each selected slot at each timestep across traces. The outcome is a single results time series slot for each selected slot.

See Analyzing Data Sets in Solution Approaches for more information on interactive use of this action in the Ensemble Data Tool.

For more information on a similar action to visualize the ensemble data set, see Visualize Ensemble Data Set.

Results are written to a set of series slots or agg series slots, one for each slot included in the analysis. Results can be written to the same object as the source slot, a results data set object, or both. When written to the same object as the source slot, the results slot’s name is created using the template: “<slot’s object>.<slot name> <results slot tag>”. For example, if the slot “Res A.Inflow” participates in the analysis and the Results Slot Tag is “Median”, then results associated with that slot will be written to the slot “Res A.Inflow Median”.

When written to a results data set object, the results slot name is created using the template: “<results data set name>.<slot’s object> <slot name><results slot tag>. For the same example of the slot “Res A.Inflow” and the Results Slot Tag of “Median” and a Results Data Set Name “Analysis Data Set,” the results will be written to the slot “Analysis Data Set.Res A Inflow Median”.

If the Write Results to Simulation Objects is “yes”, the action will create the data set series slot if it does not already exist and, if it does exist, resize it as necessary to the minimum required dimensions. All values are given the input (I) flag. If the results slot is an agg series slot and the results slot column value is other than zero, the results are written to that column of the results slot.

If the Write Results to Data Set is “yes”, the action will create the data set series slots on a new or existing Ensemble Data Object with the given tag in the slot name. All values are given the output (O) flag but are read only.

In the Analysis Type setting, specify the statistic to compute for each timestep across traces. Options are:

For the above function, note that three arguments are used, values, slot, and obj. The date is defined but not used in the body

Apply a window layout created with the Window Layout Manager. See Window Layouts in User Interface.

Clear the values set by a DMI (by using the DMI invocation manager functionality).

Clear the values on a set of Scalar Slots (i.e. set them to NaN).

Clear one or more values on a set of Table slots (i.e. set them to NaN).

Compute duration curves for a set of series slots across multiple traces and timesteps from an ensemble data set. (For more information on Ensemble Data Sets, see Ensemble Data Tool in Solution Approaches.) The results are written to table slots (one results table slot for each input slot) with a format similar to a statistical table slot using the Duration Curve function (see Statistical Table Slots in User Interface) with all of the slot values sorted (ranked) from largest to smallest. The results table has five columns: Percent of observations equaled or exceeded, the slot values, Rank, Date, and Trace.

Results are written to a set of table slots, one for each slot included in the analysis. Results can be written to the same object as the source slot, a results data set object, or both. When written to the same object as the source slot, the results slot’s name is created using the template: “<slot’s object>.<slot name> <results slot tag>”. For example, if the slot “Res A.Inflow” participates in the analysis and the Results Slot Tag is “Duration Curve”, then results associated with that slot will be written to the slot “Res A.Inflow Duration Curve”.

When written to a results data set object, the results slot name is created using the template: “<results data set name>.<slot’s object> <slot name><results slot tag>. For the same example of the slot “Res A.Inflow” and the Results Slot Tag of “Duration Curve” and a Results Data Set Name “Analysis Data Set,” the results will be written to the slot “Analysis Data Set.Res A Inflow Duration Curve”.

The action will create the results table slot if it does not already exist and, if it does exist, resize it and change column units and column labels as necessary.

Perform a multiple linear regression analysis on an ensemble data set. (For more information on Ensemble Data Sets, see Ensemble Data Tool in Solution Approaches.) The dependent variable and independent variables must be scalar slots. The primary outputs, the regression coefficients, are written to one table slot. Four other table slots are written out with statistical information about the solution quality. Details are provided below.

The Compute Regression action uses the ordinary least squares approach to compute the regression coefficients for a linear equation of the following form.

The dependent variable and independent variables are scalar slot outputs from an ensemble that are part of an existing ensemble data set.

Results can be written to an existing object on the workspace (not an ensemble data set object), a results data set object, or both.

The five results table slots from the Compute Regression action must be specified in the associated five settings. Leaving one of the result slot name settings empty will result in an error when the action is executed. If the results slot does not exist, it will be created when the script action executes. If the results slot does exist, it will be resized as necessary to fit the regression results. The units on each of the columns of the results slots will be modified as necessary to have the appropriate units from the regression analysis. For results slots on standard objects (non-data set objects) row and column labels can be edited. Any existing column and row labels will be maintained. Results slots written to results data set objects will always have default column and row labels that cannot be edited. The five results slots are described below.

Set Series Slot values within a time range.

Set a value on a set of Table Slots at the specified rows and columns.

Specify a script variable and the default value; other actions can be dependent on the value of the variable. In the dashboard, the script operator can select the value from the valid values; dependent actions will then be executed or not based on their settings. For more information on using Script Variable Values for conditional execution of actions, see Script Variable Values and Dependencies.

Set the time range for the specified objects.

Set the time range an timestep size for the specified slots.

When the timestep specification is something different than the Run Timestep, symbolic datetime math for the Start Date and End Date settings (for example, Start Timestep - N Timesteps) is computed as follows. Start Timestep and Finish Timestep are the times for the Run Control Start Timestep and Finish Timestep at the time of the script action execution. The N Timesteps are the timestep size for the slot from the Timestep setting. Then the resulting datetime is rounded up to the nearest timestep based on the Timestep setting.

Visualize data for an ensemble data set. Currently, this action will create a plot of line curves:
