Configuring and running a loss group analysis

A loss group analysis enables you to combine two or more sets of loss results from different analyses into a single loss view, or group, which is then available for use as input to subsequent processes or analyses.

Procedure

To run a loss group analysis:

  1. Open a project and then open a set of results in the Results pane.
  2. Under Run Analysis, select Loss Group.

    The Analysis Options pane for the new loss group analysis opens.

  3. To include results from other projects, clear the Show only results within this project check box.
  4. Select the results (two or more sets of results) that you want to group.

    The selected analysis results must have been generated using the same event sets.

    Touchstone automatically selects the Storm Surge and Demand Surge options based on the detailed loss analysis settings specified for the loss analysis results selected for grouping. You cannot change these options.

  5. In the Additional Details section, select EP by Peril, EP by Model, or both to see Peril and Model columns in the Summary EP table.

    To display Peril and Model columns in the Summary EP table, you must have configured the input tables to include these output options.

  6. In the Aggregate to field, select Event Total (the default) or Detailed as the geographic resolution for the aggregation.

    The Detailed option aggregates to the common detailed resolution across the analyses that you are grouping.

    Select Detailed to aggregate to the subarea level when the loss results you want to group were originally saved at the subarea resolution. The results grid includes a Geographic Resolution column so that you can identify the results that were saved at the subarea resolution.

  7. Click Analysis Management to configure analysis output options.
  8. In the Analysis Name field, leave the default name, which includes the type of analysis, or enter a unique, alphanumeric identifier.
    Tip:

    Entering some combination of the exposure view name along with the analysis type enables you to quickly find result sets in the Activity Monitor.

  9. Click Verify.

    The loss group analysis verifies whether the selections are valid for generating a loss group.

  10. Click Run.

    The application adds the project to the Activity Monitor queue for processing when the required system resources are available.

  11. View the loss group analysis results.

    By default, the Loss Groups Analysis table displays consolidated aggregate and occurrence results for the different financial perspectives.

    If the results included zonal results, you can view the results by zone. In the Summary EP Table Zone table, select a target. Then, in the Zones area on the ribbon, select the zone or zones to include in the results grid. The results change as you select each zone. You can also view results by one or more perils.

    If you saved losses by sub-peril when configuring the detailed loss analyses, the loss groups analysis results grid includes a Peril column that combined the losses for the sub-perils.
