Bootstrap values for hierarchical tree based on distaance matrix
I would like to get an hierarchical clustering tree with bootstrap values indicated on the nodes, as in pvclust. The problem is that I have only distance matrix instead of the raw data, required for pvclust. Is there a way to get it? fit1 <- hclust(dist) # an object of class '"dist" plot(fit1) # dendogram without p values library(pvclust) fit2 <- pvclust(raw.data,

problematic p values for Dixon Q test
I am using R dixon.test in order to perform Q test for detection of outliers. The p-values for high Q values are consistent with the table in Rorabacher, D.B. (1991) http://www.flworkshop.com/sscs/dixon_test.pdf, but it seems that small Q-values get problematic p-values. For example: dixon.test(c(0.324,0.5,1,1.324),two.sided=T) Q = 0.324, p-value = 1
