st: "testing" a cluster analysis

["Adam Seth Litwin" <aslitwin@hotmail.com>]

Hello.  I just ran a cluster analysis, not a technique I use frequently.  I 
have seven binary variables forming, at the moment, five clusters.  I 
thought a useful exercise would be the following:

For each of the seven variables, examine its mean in all five clusters.  
Then, run an F-test to show that the means are not equal across all five 
clusters.

So, for example, I type
- tabstat  var1, by(CLUSTER) stat(n mean)

But, I'm not sure how to run the F-test.  Really, I am doing a group 
comparison of means.  But, I cannot use

- ttest var1, by(CLUSTER)

since there are more than two clusters.

Any thoughts?  Thank you for your help.  adam
