Performing Risk Analyses with Risk Pipelines in SAS Risk Engine

[#1]

The purpose of this blog is to discuss how you can use SAS Risk Engine to perform risk analyses through the use of risk pipelines. You can use risk pipelines to create the risk environment, score counterparties, evaluate portfolios, and explore results. Furthermore, with the SAS Risk Engine interface, you can complete many of the same activities that can be accomplished through code. You can configure, execute, and explore the results of a Risk environment all from a browser in a low-code environment.

Some key business objects to keep in mind Methods and maps are objects that you reference in your pipeline. Evaluation and scoring methods are created on the Risk Methods page. Maps are created from the Maps page (see screen capture below that shows the available pages in the user interface).

In the pipeline, you use the following action nodes to add these programs to the pipeline.

A method program consists of a set of computational statements that the risk engine uses to compute one or more output variables for specific types of objects in your portfolio data.

Risk method maps show the relationship between risk methods and specific types of objects in your portfolio data.

What is the process of using a risk pipeline for your analyses?

You follow a step-by-step process in the SAS Risk Engine user interface that is similar to the one used when using SAS Risk Engine through code.

You begin with a risk pipeline, and you add functionality to the pipeline by adding notes to it. Keep in mind that whether you use SAS Risk Engine through code or the user interface, several input tables are required to perform the risk analyses. These input tables need to be placed in memory in Cloud Analytic Serves (CAS) before they can be used in a pipeline. Whichever nodes you add to the pipeline can then be configured. See screen capture below that shows a successfully run risk pipeline containing nodes.

The first step, creating a risk environment, is automatically created for you during pipeline execution, so there are no actions you need to take to complete this step.

After you configure a pipeline, you just need to submit the run to generate analysis results. The risk engine performs a few prerequisite tasks and then runs all the nodes you’ve configured in the pipeline sequentially.

You can then review the results for the pipeline itself and for each node. You can explore tables in SAS Visual Analytics and in SAS studio. Furthermore, depending on the configuration of the pipeline, results might be available for review in SAS Risk Explorer.
