wanted to know the simplest way to compute clopper Pearson confidence interval!!

[SAS_taozi]

I wanted to compute clopper Pearson confidence interval for the all the variables I have and wanted to know what's the simplest way. A sample variable I have can be  

ID	test
1	Y
2	Y
3	N
4	.
5	.
6	N
7	N

so among the 7 subjects, 2 were missing, 3 had no test, 2 had tested. I want to model the probability of being tested in SAS

It's an option in PROC FREQ.  *See The FREQ Procedure and Example 47.4 Binomial Proportions 

Here's a usage with your data:

data have;
  input ID  @3 test $1.;
datalines;
1 Y
2 Y
3 N
4  
5  
6 N
7 N
run;

proc freq data=have;
  tables test / binomial (clopperpearson) ;
run;
