In this tutorial, you'll generate a narrative using the Descriptive Statistics app. Before selecting the data fields to be analyzed, you must consider the data requirements for this app.

Some data requirements — field names and formats — are the same for each NLG app. See NLG Apps reference > Data requirements for details.

Other data requirements — the minimum number of required fields and the supported combinations of aggregation and entity types — vary by app. You can find these details in the NLG Apps Directory.

The Descriptive Statistics app has the following requirements:

  • Minimum number of fields: one measure and one non-time dimension.

  • Supported combinations of aggregation and entity types:
