Elbow criterion
Hi, I would like to cluster a dataset with the ward algorithm. That works fine. But I can't find a method to plot the structure chart to estimate the "elbow crterion" for the number of clusters. Can someone tell me how I can do it? Thanks for your help. Dominik

Dissimilarity matrix and number clusters determination
Hi, I already have a dissimilarity matrix and I am submitting the results to the elbow.obj method to get an optimal number of clusters. Am I reading the below output correctly that I should have 17 clusters? code: top150 <- sampleset[1:150,] {cluster1 <- daisy(top150 , metric = c("gower") , stand = TRUE , type = list(symm

How to determine the number of dominant eigenvalues in PCA
Dear All, I want to know if there is some easy and reliable way to estimate the number of dominant eigenvalues when applying PCA on sample covariance matrix. Assume x-axis is the number of eigenvalues (1, 2, ....,n), and y-axis is the corresponding eigenvalues (a1,a2,..., an) arranged in desceding order. So this x-y plot will be a decreasing curve. Someone mentioned using the elbow (knee)

Optimal Y>=q cutoff after logistic regression
Hi, I understand that dichotimization of the predicted probabilities after logistic regression is philosophically questionable, throwing out information, etc. But I want to do it anyway. I'd like to include as a measure of fit % of observations correctly classified because it's measured in units that non-statisticians can understand more easily than area under the ROC curve, Dxy, etc.

Stereo dropping to mono with libopus 1.2 RC
Hello Jean-Marc, yes, it works for both 32 and 48 kb/s. Also this option marginally increases the size of the file which is understandable. I tried a few other music files and found that this stereo narrowing happens not only in the case of track I submitted (although in smaller scale) so it would be great if the final libopus 1.2 had officialy a parameter to force music "mode" of

Most problems are close by the check failure. If you want to check extra fancy, dump the CHECK-LABEL region.

Tendonitis and R users
Hello This request asks something beyond the technicalities of the R language, I would like to ask you wonderful people if you have ever suffered as programmers ( or de facto programmers like myself though I am a 'research assistant') from tendonitis and how you coped with it, i have golfer's elbow on both sides.

smbcquotas tells me that "quotas are not enabled"
I have a setup of Ubuntu 8.04 running Samba 3.0.28a. Connected to our network I have a buffalo linkstation acting as Network Attached Storage (NAS), which I have successfully mounted on the local file system. Using smbcquotas I believe I can set up a quota for each user on the NAS. To get started, I run the command: smbcquotas //192.168.1.4/share -S FSQFLAGS:QUOTA_ENABLED -A

Stereo dropping to mono with libopus 1.2 RC
Hello, I'm not a programmer or Opus developer but I tried to test the sound quality of a music file (Nick Warren - Devil's Elbow, freely available from the author's Soundcloud account) encoded with libopus 1.2 RC1. I used Windows binaries from free-codecs.com. I noticed that in the case of my selected music file (which is generally harsh on lossy codecs as it's necessary to

SIP and NAT - best practices?
Thanks Moises. I was kind of hoping that, at least if I hosted my Asterisk server somewhere where there was no NAT for the * box that the SIP phones wouldn't create any issues. How do you people with Hosted PBX handle the deployment of SIP phones behind NAT firewalls? Is it just elbow grease and configuring every single phone for the customer, or is there a way? Mike you can redirect

R on fairly large machines
Hi, We are considering using R on a large problem that will require four 64 bit cpu's and 64Gb of ram and some flavor of unix. We are just wondering if R is going to be happy in this environment. If have experience with this please let me know. Thanks, Allan Tingey al at genetics.utah.edu

Number of dimension in Multidimensional Scaling
Hello! Very often one can hear that MDS usually ends with two-dimensional solution. Of course, there are methods, like Scree-test (proposed by Kruskal and Wish, 1981), to determine optimal number of dimensions. However, I am trying to find references to this two-dimensional gold-standard. Can anyone point me to authors which explicitly states that two-dimensions are typical and easiest to
