DBMS_STATS package can gather global statistics at multiple levels as specified by the granularity parameter.
ANALYZE command collects statistics only at the lowest level.

Oracle recommends to use DBMS_STATS mainly to collect optimizer statistics in 8i and 9i. For 8i and below use analyze.
Remember to monitor the table to keep the stats upto date.
