SET AUTOTRACE only reports on DML (select, update,insert , delete)
statements.
The commands you ran were DDL commands 
If you notice at the end you did a count of the plan_table and that reported
statistics

Hi:

I am trying to understand why sqlplus did not display stats when I run
"analyze table ..." and "create index ..."?

TIA.
