How to use PROC CORRESP MCA pre-process for clustering?

angelinaliu — Thu, 04 Sep 2014 20:07:54 GMT

I want to use PROC CORRESP (MCA option) as a pre-processing for clustering. The purpose of this is to transform categorical variables to continuous variables. Does anyone have any sample codes or examples for this? How can I create output dataset from CORRESP (MCA option) and then do the hierarchical clustering with ward criteria?

Thanks.

I don't think you can use PROC CORRESP to transform categorical variables to continuous variables. It decompose cell chi-square into X axis and Y axis , therefore you can make some cluster idea,but that is only for CATEGORY variables.

I can kind of see a clunky way of doing this. After PROC CORRESP does its thing and you get the X and Y axis values, you could use PROC DISTANCE to get a single continuous value, or just use the X and Y axis values as continuous variables.

Yeah. use the X and Y axis values to cluster, right ?
