That reference is not to optimizer statistics but rather to extended sql trace statistics. You can use dbms_job to schedule dbms_stats to fix your issue. Cron is also available if you want to do it outside the database for some reason.

Do I need to set some parameter to enable these on 10g or they have same behavior as of 9i?
