I've never seen compute statistic put there before!

using index syntax does not belong here either.
It's used to create index when you create constraints like Primary key or Unique key.

JR's suggestion should work.

JR2003:
You can use Compute Statistics while Creating Index

Use the following:
create unique index FLOG_PREFIX_DATE_inx on FAX_LOG
 (SUBSTR(FLAG_CONFIRM,5,10))
   compute statistics;

If you want to create the index on tablespace tsdix then

create unique index FLOG_PREFIX_DATE_inx on FAX_LOG
 (SUBSTR(FLAG_CONFIRM,5,10)) tablespace QSA_INDEX
   compute statistics;

To create the tablespace use JRs sugestion.
 

To create statistics on index analyze the table as follow:
   
 ANALYZE TABLE fax_log COMPUTE STATISTICS;

or

exec DBMS_STATS.GATHER_TABLE_STATS(OWNNAME => NULL, TABNAME => ' fax_log', CASCADE => TRUE);

I agree with schwerner's suggestion.

Analyze the table after the index has been created.  This is because the optimizer will not understand the correct cost until the table has been re-analyzed.  Not sure if an enhancement has come through to address this, but that has definitely been the case.
