Ranking Analysis
About the narrative
Details covered in the analysis
The narrative includes:
an overview section that summarizes ranking changes in a measure (Profit) for the highest priority dimension (Country). For example:
subsections that describe top and bottom ranking changes and when they happened, for up to three dimension drilldowns. For example:
Note
The order of drilldown is determined by the order of dimensions set in Step 2 of the NLG Apps wizard: Data configuration.
The narrative wording depends on the selected aggregation types, referring, for example, to total, average, minimum or maximum values. For the Percentage, Rating and Ratio entity types, total values are omitted from the narrative as it does not make sense to sum up non-additive measures.
The app attempts to describe as much detail as possible, but when there is too much to describe the narrative will not report on dimensions below the second dimension drilldown.
Data requirements
All NLG Apps have the same data requirements for supported formats and field names. See NLG Apps Data requirements for details.
In addition, each app has specific data requirements:
