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 (y axis) against number of clusters (x axis). Is there a way to do this in R base or cluster packages that I'm missing? As an alternative I've attempted to write a funct...

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

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...

...umber 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) method to find the point that the maximal curvature of this curve occurs. The number at this point would be the number of dominant eigenvalues. But I could not find any reference papers on this idea. Does anyone has tried this method or knows more details on this? Thanks for your point. F...

...ified because it's measured in units that non-statisticians can understand more easily than area under the ROC curve, Dxy, etc. Am I right that there is an optimal Y>=q probability cutoff, at which the True Positive Rate is high and the False Positive Rate is low? Visually, it would be the elbow in the ROC curve, right? My reasoning is that even if you had a near-perfect model, you could set a stupidly low (high) cutoff and have a higher false positive (negative) rate than would be optimal. I know the standard default or starting point is Y>=.5, but if my above reasoning is correct, th...

...my model I know I need something: def self.chopem(tag) Tag.find(:all) end I think I lack the understanding of how the array that comes back from the database is constructed. Can anyone explain this so I can chop those words up and sort them with the .uniq method? Apologies if this is arse for elbow. -- Posted via http://www.ruby-forum.com/.

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

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 use quite a high bitrate to make differ...

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 the ports of the router as well. Or you can configure your SIP phone to use a STUN server. Please read in voip-info.org about SIP NAT, there are good suggestions. regards On 1/20/06, Michakl G...

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

At the very least, you'll need some familiarity with the Windows toolchain and be prepared to apply a fair amount of elbow grease. -pd (crosspost to r-help removed) On 29 Dec 2016, at 22:04 , Paul Bernal <paulbernal07 at gmail.com> wrote: > Dear Jeff, > > Thank you for your fast and kind reply.
