Hierarchical cluster analysis (binary data)

[Monica Rocha]

1. I tested the commands for binary variables:

 cluster average linkage var1 var2 var3, measure(matching)

 cluster complete linkage var1 var2 var3, measure(matching)

  cluster average linkage var1 var2 var3, measure(Jaccard)

  cluster complete linkage var1 var2 var3, measure(Jaccard)

2. Then, I used the Stata commands (Calinski-Harabasz and Duda-Hart) to check the number of groups

3. But, I can't generate the dendrogram
“too many leaves; consider using the cutvalue() or cutnumber() options”

What should I do?
