I was having problems with Proc Freq.
I was looking for the estimated proportion and CI with two levels.
Let's use Example 3.1 under SAS help as an example.
What is the proportion and CI for the students with "Blue" eyes and "Dark" hair?
I create another new variables and combine the two variables.
here is how I do it.
proc freq data=new2;
tables eyehair/binomial(level="blue dark") alpha=0.05;
Is there a easier way to do this?
