Dear Statalisters:
I am not familiar with cluster analysis and don't have an easy access to the manual on this topic. However, I have a group of 21 observations with one variable (a score) and would like to create three "homogeneous" groups.
I found the -cluster kmeans- command. Here are my command lines:
gsort - finance_aggregate
cluster kmeans finance_aggregate, k(3)
Each time I run these commands, I get a different result (i.e., a different clustering: the three groups are different). I looked at the help file but don't understand. (It might be related to the start option but I am not sure).
Is there a way to obtain the same result everytime?
Best regards
Herve Stolowy
