probabilty calculation in SVM
Hi All,
In package e1071 for SVM based classification, one can get a probability
measure for each prediction. I like to know what is method that is used for
calculating this probability. Is it calculated using logistic link function?
Thanks for your help.

Feature selection
Hello,
I want to do feature selection for classification purpose (using lda). Can someone point me to any R package or S-plus package for this? Something like SFS or SFFS method would be useful for me.
Thanks.

predict.glm
Hi All,
Sorry for this is a very naive question.
I am trying to do binary classification (male vs female) using glm using following data:
X1 X2 X3 Class
2.3 4.5 2.1 Male
0.9 3.2 1.6 Male
1.7 1.8 2.6 Feamle
I am trying to use predict.glm for prediction with type="respose" which gives the predicted probabilities as per documentation.

fBasics package: dnig
Hi,
I am trying to calculate probability density of normal inverse gaussian distribution. I am using dnig function of fBasics package. However, I am getting following result. The density at x = 0.003042866 is:
> dnig(x= 0.003042866, alpha=5.184868, beta= 0.11841, delta= 0.06038513, mu= -0.0003520626)
[1] 6.550251
I am not sure why it is 6.550251. Can anyone tell me why density is more than

Dear Colleagues,
I would like to do classification using logistic regression. Which R package can I use?
Also is there any package for feature selection for logistic regression based method?
Thanks a lot in advance.
Happy holidays.

glm vs multinom
Dear Colleagues,
I am doing two class classification using logistic regression. I realized that I can either use "glm" function or "multinom" function. I know "multinom" is used for multiclass classification. But if I was it for binary classification, I was wondering if there is an difference in the results compared to "glm" results.
Thanks in advance.

XCP and OpenXenCenter
I just noticed OpenXenCenter (aka OpenXenManager) that is an open source
replacement for Citrix's XenCenter. This tool works with XenServer.
But as per the blog entry:
http://blog.xen.org/index.php/2010/02/09/xen-cloud-platform-installation/
it is also supposed to work with Xen Cloud Platform. XCP is licensed
GPL2 and is a combination of multiple packages.

[PATCH] Dont bypass compiler driver for Dependency generation options
We can let compiler driver pass the right options to preprocessor after
processing -Mxy options, right now its bypassing the gcc driver and
handing them straight to cpp
This also helps in other compilers processing these options correctly
for their preprocessors consumption

rsync errors
Ah... there's your answer. ssh is working fine, as you say, but you're invoking rsync without telling it to user ssh, so it's using rsh. If you've got this, you don't need rsyncd.conf. The syntax you're using tells rsync to use an external transport.
rsync -e ssh file rmt_host:/tmp

ChanSpy with alphanumeric SIP channels [1.6.2]
Hi,
I'm using SIP users of the form 'ab_12345' (two letters, underscore, 5
digits). ChanSpy is working fine for listening in to conversations
initiated by these channels, and I can use '*' to randomly switch
channels. However, is there any way in this scenario to be able to
switch ChanSpy to a specific channel by typing in a ...# key sequence
during a spy session?

font metrics updated on each program launch
Everytime I start a program with wine-20010629 on Red Hat Linux, font
metrics get updated.
I am getting fonts through the Xserver (no xfont server)
(currently M$, ghostscript, Type1, misc and 75dpi fonts)
Is this behaviour normal?
Everytime this happens, I get lots of output like
fixme:font:LFD_InitFontInfo DBCS fonts like '-urw-century schoolbook
