Descriptive statistics functions analyze and explore a database.

Descriptive statistical analysis is valuable for the following reasons:
  • Provides business insight.
  • Uncovers data issues that jeopardize the accuracy of analytic models based on the data if you do not not correct or compensate for the issues.
  • Isolates the data used in building analytic models.

    If you identify an outlying value, you can include or exclude the value depending on the business problem.

  • Helps determine the suitability of data elements for model input and suggests transformations.

    Statistical processes used in analytic modeling require a certain type of data distribution.

Descriptive statistics functions handle NULL values with aggregate functions in their generated SQL.
