Visualizing associations between categorical variables

[palolix]

Dear SAS Community,

I was looking for a way of visualizing the association between different categorical variables (nominal and ordinal variables). Since a heatmap will probably not work for categorical variables I think that a correspondence analysis should be a good option. Is it ok to include nominal (more than two levels) and also ordinal variables together in a correspondence analysis?

I would greatly appreciate your feedback!

Yes. You could could . since PROC CORRESP is just decomposing the chi-square value of contingency table, no matter this category variable is nominal or ordinal .

proc corresp data=sashelp.heart all chi2p;
tables bp_status,weight_status;
run;

And I also think you could use heatmap to visualize it. Here is an example:
