Tests for the need of cluster analysis
Does R have the capability to perform tests for the need of clustering analysis (e.g., in prabclus)? I am using panel data with two-way fixed effects but am unsure about whether I should be using a cluster option as well to estimate my model.-- View this message in context: http://r.789695.n4.nabble.com/Tests-for-the-need-of-cluster-analysis-tp3488097p3488097.html Sent from the R help mailing l...

R CMD build error with data files
Dear list, I want to update my prabclus package which I haven't done for quite a while. In the previous version, I had .dat files in my data subdirectory, which I read using .R files. Now R CMD check gives me a warning that .dat files are no longer accepted there. So I changed my filenames to .txt, but actually some of these fil...

stability measures for heirarchical clustering
...ing (using sample and generating a consesus tree with a web based tool CONSENSE) but i wondered if there have been any advances on the "bootstrapping clustering" front? In terms of finding stability in sub sections of the clustering I'm thinking of modifying the jaccard function from prabclus to look at pairwise similarities in different cluster partitions of sub-samples of the data, with high similarity being indicative of stability. I wondered if anyone has already looked at stability measures for clustering (particularly thos which interface with hclust), and if any are available al...

Jaccard dissimilarity matrix for PCA
Hi I have a large dataset, containing a wide range of binary variables. I would like first of all to compute a jaccard matrix, then do a PCA on this matrix, so that I finally can do a hierarchical clustering on the principal components. My problem is, that I don't know how to compute the jaccard dissimilarity matrix in R? Which package to use, and so on... Can anybody help me? Alternatively

spdep question
...with errorsarlm. However, I am not sure how to make a valid nb object out of my neighborhood. As far as I have seen, there is no documentation for nb.object. I have done the following: class(pschmid$nb) <- "nb" # pschmid is a prab object as generated from function prabinit, package # prabclus, and the neighborhood looks as follows: > unclass(pschmid$nb) [[1]] [1] 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 [[2]] [1] 1 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 [[3]] [1] 1 2 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23...

outlier threshold
For the analysis of financial data wih a large variance, what is the best way to select an outlier threshold? Listed below, is there a best method to select an outlier threshold and how does R calculate it? In R, how do you find the outlier threshold through an interquartile range? In R, how do you find the outlier threshold using the hist command? In R, how do you find the outlier threshold

Clustering and bootstrap
Dear Listers, I emailed the list a few days ago about how to bootstrap a community matrix (species by sites) and get a consensus tree with node support. A friend pointed out that a similar question remained unanswered in 2004. I wish to re-word my question: is anyone aware of a package / method to obtain a majority-rule consensus tree from x distance matrices ? Is anyone using R to generate
