Thanks for comments. Yes, inclusion/exclusion of the unform makes biologically sounds results. That's why the idea of comparison of non-uniform similarity pattern with just uniform one. The advises agree with my expetation, the only doubt was that the uniform component includes only two variables for each object which makes apllication of any distance measure a little bit unreasonable. I shall do that with NTSYSpc. ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, October 22, 2003 4:20 PM Subject: RE: just uniform component
