C-Software for Fixed Point Cluster analysis

Fixed Point Cluster analysis is a new approach to cluster analysis.
It can produce overlapping, non-exhaustive clusters. Fixed Point Clusters are
data subsets which do not contain any outlier, but all other points of the
data set are outliers w.r.t. the Fixed Point Cluster. For further
explanations load the papers from my homepage. FIXMAHAL is a software for
finding spherical shaped clusters by means of the Mahalanobis distance.
FIXREG is a software
for finding linear regression clusters. Both programs are written in
C. At the moment, FIXREG is better implemented and tested than
FIXMAHAL. The R-package fpc (see above)
provides a more comfortable implementation with better functionality
(much better for FIXMAHAL), but it is slower.
The LINUX/UNIX-version is recommended.
