I use SAS9.4. I would like to do a exact analysis of s by r table where the covariate is nominal and the response is ordinal. Also this is an analysis of categorical data, so we observe the frequency of each covariate*response level. So the data should look something like data example; input covariate $ response $ count @@; datalines; cov1 bad 3 cov1 moderate 4 cov1 good 0 cov2 bad 4 cov2 moderate 1 cov2 good 2 cov3 bad 5 cov3 moderate 2 cov3 good 1 ; The sample size is quite small, so I would like to use exact analysis. I suppose I can do something like froc freq order=data; weight count; tables covariatename*outcomename / exact run; But, this should give just a general association, not a "mean score differ" type of result. What kind of option can I use to do this exact analysis? Thank you for your help in advance.
