/I would appreciate some comments on proc freq.
/     1. suppose, the independnt var. is X whilst  Y is the
/dependent var.  then how i would write the table command:
 
/              a. tables Y * X  ;   OR
/             b.  tables X * Y  ;
 
Either way you will get the same information, that is, the counts will be
the same for every intersection of the levels of X and Y,
but the report will be sorted by your first variable.
 
be sure to check that missing are present and accounted for:
tables X * Y /list missing;
 
note: the parameter 'list' turns off the column and row sums;
 
if either X or Y are mising, then that summary row will be counted and noted
in the
'Frequency missing = ??' line at the end of the summary.
