Dear All,

I am working on a small dataset and most of the variables are skewed. In
this data 2 'observers' give an opinion and in some instances they do agree.
I want to find out the difference in response when they both agree on a

For example in this dataset the age of the people was given, and the two
observers are asked to state a preferred method of  treating the subjects
and I want to find out using non parametric methods if there is any
difference in age when the 2 observers choose the same method of treatment.
That is if the method is 'A'  for example, I am interested in any difference
when they choose method A.  Note that in some cases they both agree on A and
in some cases they do not and so the groups cannot be mutually exclusive. Is
there a way of handling this in STATA such that if observer 1 says yes 15
times and no 12 times, while  observer 2 says yes 18 times and no 9 times
then I can only compare when they said yes. However I want to treat the
responses as if there were no times when they said ties together even though
they did.
