proc freq for two way table with proc template

[Ronein]

Hello

I am using proc template to edit output of two way freq table.

The calculation of Relative Frequency is not accurate and I want to ask why and how can we solve it?

For example: 

For  Make=Acura and Type=Sedan frequency=5 so Relative Frequency should be 5/428=1.17%

But in the output you can see that we get 1.16%

Why there is a difference???

proc format; 
picture pctfmt low-high='000.00%';
run; 


ods path work.templat(update) sashelp.tmplmst(read); 
proc template; 
edit Base.Freq.OneWayList;
edit Percent;     
header="; Relative Frequency ;"; 
format=pctfmt.;   
justify= on;
end;
edit CumPercent; 
header = ";Cumulative;
Relative Frequency;"; 
format=pctfmt.;
justify= on;
end;   
end;
run;


proc freq data=sashelp.cars;
tables Make * Type / list;
run;

Nothing to do with proc template and everything to do with your picture format. 

Consider:

proc format; 
picture pctfmt low-high='000.00%';
run; 

data _null_;
  X=1.1688; putlog X= pctfmt.;
run;

X=1.16%

Thank you.

Can you help with the full code?

I didn't  understand how to apply it

proc format; 
picture pctfmt low-high='000.00%';
run; 

proc freq data=sashelp.cars;
tables Make * Type / list;
format ???????? pctfmt.;
run;

You are editing the one-way list template but are outputting a 2-way list.

Do you have two way template?

Sorry I am not a friend of proc template's. 🙂

Why don't you use proc tabulate?

proc format; 
  picture pctfmt low-high='000,009.00%' (multiplier=100);
run; 

proc tabulate data=SASHELP.CARS;
  class MAKE TYPE ;
  table MAKE all, (TYPE all)*pctn=' '*f=pctfmt10.2;
run;
