Hello All, I'm looking to test a variable in a logit model (glm(..., binomial(link="logit"))) for exogeneity (endogeneity). At this point I am planning to try implementing Jeffery Grogger's "A Simple Test for Exogeneity in Probit, Logit, and Poisson Regression Models", Economic Letters, 1990. To do this, I need to be able to do an instrumental variables NLS

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. --

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

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. A mutual cluster is a set of observations whose largest

Hello, I've just downloaded and installed the RAqua onto my Mac and I have R up and running fine. Now I'm trying to get 'ape' downloaded and installed and having quite the difficulty. I am following the directions specified under 'Installing packages' where packages can be downloaded and installed from within R. I get the following error messages: 1: argument

Hi There, I'm working on some cluster analyses on a large data-set using hclust with Wards method and Manhattan (city block) distance measures. I've created dendrograms to illustrate the clustering criteria, but would like to create a plot to examine for the classic elbow criterion to use in determining the best number of clusters. Ideally I'd like to plot percent variance explained

Dear all, I'm trying to rerun some data linkage exercises in R (they are designed to be done in SPSS, SAS or STATA) The exercise in question is to relabel the column "treat" to "1", if "yearsep" is smaller than 1988 and columns "proc1"-"proc3" contain the values 56.36 or 59.81. My pathetic solution to do this in R currently looks like

Are there any R rpm's for Mandriva 2008.1? I found a couple of dodgy ones that wouldn't install so far (rpmfind.net). (Sorry that seems so far the only Linux distribution that recognizes my hardware on my new laptop correctly. I'm more familiar to Fedora and Suse so perhaps I'm just doing something wrong?) Joanne

Dear all, I have been using the contrast library in my teaching for the last couple of years and am right in the middle of this year's round. In the last week R has been updated to version 2.14.0 on our computers. This has had the unfortunate effect of meaning the contrasts library no longer works, as the Design library is no longer available. I wonder if anyone has a fix for this...or

Hi All! I am interested in testing whether the means for the data I am investigating are equal to a specific value - let's say 0.01. I have already run a one-way ANOVA and know that the differences in the means are not significant, so now I want to know what values the means take on. "otestme" is the data I am working with (it would be hard for me to get into a form that would be

Hi, Can anyone shed any light on why "reaper" (whilst seemingly working re restarting my mongrel ruby process) does not pick up changes to my application? (e.g. changing a title in a view for example). It''s like the "mongrel_rails start etc..." is just restarting the current process but ignoring the new details re where the new application directory is. That is
