would like to retrieve the parameters used in gather stats procedure

suppose if i have executed the below procedure:

exec dbms_stats.GATHER_TABLE_STATS(ownname =>'PHERMES',TabName=>'PAYMENTRETURN',estimate_percent => 30, method_opt => 'FOR ALL COLUMNS SIZE AUTO',cascade => TRUE, DEGREE=>DBMS_STATS.AUTO_DEGREE);

How can i retrieve the parameters used above like estimate_percent,method_opt,cascade and DEGREE later if i want to cross-check......
