Cluster analysis with categorical variables ?

Hi Bhaswati, I had similar kind of data in one of my clustering project. I used expected maximization clustering techniques which is based on prior probability distribution and likelihood based algo. In fact you can also do Latent class analysis for such mixed type of data. I will recommend for expected maximization algo for the clustering. I do not know whether this is possible with SAS EG i used open source tool weka to do this analysis.
