Generator summary

The following table summarizes the available generators. It indicates whether each generator can be made consistent, can be linked, and is differentially private.
In the Consistency column, the table also indicates whether the generator can be made self-consistent only, or can be made either self-consistent or consistent with another column.
The Description column includes:
  • For generators that can be data-free, whether the generator is always data-free, or only data-free when consistency is disabled.
  • The possible privacy rankings for the generator. For details about the available privacy rankings, go to Privacy ranking.
