Proc Tabulate calculating percentages

I'm having problems using PROC TABULATE to calculate percentages.

 

Here is what my dataset looks like:

 

namepassmonth
name10jan
name11jan
name21mar

 

I can use proc freq to calculate the column percentages for each month, as follows:

 

proc freq data = test;
tables pass*month;
by name;
run;

 

Since I'm using the "BY" statement, it generates a separate table for each name. I'd like to use PROC TABULATE to have all the data in one table. Here is my proposed code, but it doesn't work. 


proc tabulate data=test;
class name month;
table name*month*
(n='Total'*f=4.
ROWPCTN= 'Percentage of pass')
,
month/rts=60 box='Percentage of pass';
run;

 

 

What is wrong? It only calculates the total "N" but I want it to calculate "N" for each month, as in the proc freq column percentage.

 

thank you kindly.

With a 0/1 coded variable the sum = number of ones or pass (assuming 1 means pass), the mean will give you a percentage:

 

proc tabulate data=test;
   class name month;
   var pass;
   table name*month,
         pass=''*(sum='Number pass'*f=best5. mean='Percentage Pass'*f=percent8.1)
   ;
run;

N for Pass would give you the number of tests administered that received a score.

Try adding it as a 'page'? You can also specify the levels by moving where the statistics are calculated using the ALL keyword. 

 

table name, month*
(n='Total'*f=4.
ROWPCTN= 'Percentage of pass')
,
month/rts=60 box='Percentage of pass';
