Like you said, such kind of test will not give me anything that Rand index does not, except for p-value.
The null hypothesis, in my case, is that clustering results does not match a different clustering, that someone alse did on the same data. And I do believe that this hypothesis is valid. Basicly, it's not that different from chi-squared goodness of fit test which check whether or not my data comes from particular distribution. With an exception that I don't know how to do chi-squared test in this case :) --- "Liaw, Andy" <[EMAIL PROTECTED]> wrote: > But what would such a test do that the rand index > does not?
