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.
