Subject: Fuzzy Set Ordination Web Page

I'd like to announce the debut of the Fuzzy Set Ordination Web Page at:

http://www.du.edu/~rboyce/fso/modivkabc.htmb.htmnlineSearch.cfm?OpenView/cha

Fuzzy set ordination (FSO) is a form of ordination based on fuzzy set
theory that was introduced about 12 years ago by Dave Roberts at Utah State
University.  It hasn't been used a lot, in part because software to run it
has not been available.  This is an attempt to rectify that situation.
Sample programs and data sets for both relative abundance data and
presence/absence data that are written in SAS are now freely available for
downloading; the user may modify them for his or her own data.  SAS is not
the ideal program for ordination, but it is widely available and
platform-independent.  I also hope to stimulate someone with programming
skills to create a more user-friendly software package (hint, hint!).

I've also included programs with a routine to minimize the "curlover"
effect seen in FSO (analogous to the horseshoe or arch effect of PCA).

I expect that there are still some bugs in the programs and/or the web
page.  Please send bug reports to me at the address given below and I will
fix them as soon as possible.  Other feedback is welcome, too.  Please send
me any FSO references that I have missed, too.
