To get Statistic object properties, users can be a member of the public fixed server role.

To set Statistic object properties, users must have ALTER permission on the parent table or view or be a member of the db_owner fixed database role.

To create or drop a statistics counter, users must have ALTER permission on the parent table or view or be a member of the db_owner fixed database role.

To update statistics, users must have ALTER permission on the parent table or view or be a member of the db_owner fixed database role.
