DO varclus work for binary data as well?I mean is all predictors are binary and I want to group variables.
Selection of variable from each cluster is basis which criterion?
but its very time consuming to do it for all 65 variables.
Don't use the excuse of time for shortcuts as you don't know what learning you will miss. Data experience comes from touching / exploring all the data at as low a level as possible to learn and understand how the variables relate and interact with each other. . . and then to the dependent variable. That is how data intuition is built and how data business experience is built.
