Hi All,
I am interested in a correlation measure for an ordinal variable where n is
small <10 and there is the possibility of lots of ties. Can anyone help?
Here is an example I have data from a survey for question i, x_i and y_i can
take the values {A,B,C,D,E} (A best, E worst) , n_i = 5 for all i; x_i =
{A,A,A,B,E}, y_i = {A,B,C,C,D}. So I want to compute cor(x_i,y_i) i = 1,...
Q, where Q=num. questions in the survey.
I can then look at the average per question correlation for the survey.
Best Regards,
Richard
