Hi All,

I am a new member of this site and liked the discussions that are floating in this site.I have some questions regarding clustering, can anyone please help me out with these ?

  1. In Procfastclus , how do we best treat nominal and ordinal variables (i.e. non interval variables) other than creating dummy variables
  2. Which method is best to use in Procfastclus - K means , ward's etc.?
  3. Which is the best method to validate the clustering model?

I have more than 100k observation so i cannot use proc cluster as it takes lots of time?


Please help me out with this? Thanks..
