st: "testing" a cluster analysis
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
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
