I'm looking to test a variable in a logit model (glm(...,

Probit, Logit, and Poisson Regression Models", Economic Letters, 1990. To do
this, I need to be able to do an instrumental variables NLS

Cluster Analysis - Number of Clusters
Hello,
I'm playing around with cluster analysis, and am looking for methods to
select the number of clusters. I am aware of methods based on a 'pseudo
F' or a 'pseudo T^2'. Are there packages in R that will generate these
statistics, and/or other statistics to aid in cluster number selection?
Thanks,
John.

hybridHclust (new package)
I'd like to announce the availability of a new library for hybrid
hierarchical clustering, "hybridHclust". The library has been uploaded
to CRAN and is now available.
The library implements a hybrid of top-down and bottom-up hierarchical
clustering. Along the way, the idea of a "mutual cluster" is developed.

Distance between lines
Hello,
I'm trying to assess the similarity of two lines that are represented as points (output of differential equation solvers). Is there a function or a package that deals with things like this?
Thanks,

Roots of quadratic system.
Hello,
I have a system of quadratic equations (results of a Hamiltonian optimization)
which I need to find the roots for. Is there a package and/or function which
will find the roots for a quadratic system? Note that I am not opimizing, but
rather solving the first order conditions which come from a Hamiltonian. I am
basically looking for something in R that will do the same thing as fsolve in

"chemical" plot
Hi all,
May be there is a plot which shows 3 variables in a triangle, their sum
being constant. I have forgotten its name, and a search in the engine using
"plot" did not help.
Does anyone know of such a procedure in R or S?
Thank you

Constrained optimisation
Hello,
I need to solve a non-linear optimization with non-linear constraints.
The 'nlm' routine does not seem to allow constraints. Is there a
package for solving such problems in R?
