I've uploaded to the archive a new version of Statistics::LTU.

where CPAN is your favorite CPAN site.

The changes of 2.7 are mostly cosmetic but fix some nagging
package/namespace mistakes.  I've also added a Makefile.PL that works with
some versions of MakeMaker.

>From the README:

This is Statistics::LTU, a module for Linear Threshold Units.
A linear threshold unit is a 1-layer neural network, also called a
perceptron.  LTU's are used to learn classifications from examples.  An LTU
learns to distinguish between two classes based on the data given to it.
After training on a number of examples, the LTU can then be used to
classify new (unseen) examples.

LTU.pm defines an (uninstantiable) base class, LTU, and four other
instantiable classes built on top of LTU.  Each of the four classes uses a
different training method: ACR (absolute correction rule), TACR (a thermal
annealing version of the absolute correction rule), LMS (least-mean squares
fit) and RLS (recursive least-mean squares rule).
