You can dynamically generate these meaning you can add and remove fields to the data model until you get it right. This “accelerates” (speeds up) searches on that data as Splunk just uses the values directly from the index files, rather than having to retrieve the raw events for the search. Generalized Estimating Equations. Now for the details: we have a datamodel named Our_Datamodel (make sure you refer to its internal name, not display name), an object named. An extensive list of descriptive statistics, statistical.
