OT: a weighted rank-based, non-paired test statistic ?
Hi,
Is anyone aware of a rank-based, non-paired test such as the Krustal-Wallis,
that can accommodate weights?
Alternatively, would it make sense to simulate a dataset by duplicating
observations in proportion to their weight, and then using the Krustal-Wallis
test?
thanks!

Outliers in Binary Logistic Regressions
Hallo folks,
I know I should not ask the same question again. But I have a problem I cannot solve and without the solution I am stuck and lost, unable to get along with my work!
Someone suggested I should try the code below in order to eliminate the outliers from my data. I did as I was told, but I got a negative reply. The code did not function. I am including it here so that, if possible,

Kendall package tau-a, b, and c
Hi all,
I would like to ask a question related to Kendall package. I ran Kendall
(x,y) and
saw the results. But I am not sure which tau values R reported. I have
ties in
my data set, so I want tau-b. Can anybody tell how Kendall package is
calculating tau values? I have looked at the package PDF, but I could
not find
any useful information. As long as I see from the following

Epi Info
Hello:
Does anybody knows if Epi Info, from CDC (www.cdc.gov/epiinfo) runs on Wine?
I did try AppDB first but there are no entries for Epi Info.
Epi Info is a data base for epidemiology and public-heath developed by
Centers for Disease Control and Prevention (USA) and heavilly used in
the world. It is based on Access 97 or 2000 witch I found in Frank's
Corner AppDB.
Thank you,

How to effectively remove Outliers from a binary logistic regression in R
Hallo there,
greetings from Germany.
I have a simple question for you.
I have run a binary logistic model, but there are lots of outliers distorting the real results.
I have tried to get rid of the outliers using the following commands:
remove = -c(56, 303, 365, 391, 512, 746, 859, 940, 1037, 1042, 1138, 1355)

OT: Sieve + Forward as Attachment
I know that this is technically not a Dovecot problem; however, I was
wondering if anyone knew if 'sieve' had been updated with the ability
to 'forward as attachment' a received document. I believe it has the
ability to forward a document; however, I need the ability to forward
it as an attachment if possible.
Also I believe, somewhat due to my asking for them, that sieve exits

Is it fine to upgrade to Centos 6 rpms, being at centos 5.8
Hi,
I'm currently at CentOS 5.8. After some penetration testing, found some
high severity OpenSSH issues which would require its upgrade. But till
CentOS 5.9 the latest rpm available is openssh-4.3p2-82.el5 (which I'm
currently using).
Is it fine to upgrade to CentOS 6 rpms while I'm on CentOS 5?

Extract concordance from coxph.object
Dear all,
As I said in my previous email I have just upgraded to R 2.14.0 on Windows 7. I have just run the 'coxph' function and notice that a Concordance statistic is produced. Is there any way to extract this information from the output?
E.g. can I call the concordance value independently of calling the output?
Many thanks,
Laura

Bug in concord package
Please note that there is a bug in the tie correction function in the package:

If anyone has downloaded the first package, please replace it with the second
one.

test for proportion or concordance
Hello group,
my question is deciding what test would be appropriate for following question.
An experiment 'A' yielded 3200 observations of which 431 are
significant. Similarly, using same method, another experiment 'B' on a
different population yielded 2541 observations of which 260 are
significant.
There are 180 observations that are common between significant
observations of A

Concordance and Kendall's tau in copula
Dear
I estimate a sample selection model using the Clayton copula and Burr
and Gaussian marginal. I need to derive ther Kendall'sw tau from the
concordance coefficient by integration. I came across a way to do that
in R long time ago but cannot find it again. Can somewone tell me what
to read and what to use? Thank you.

concordance correlation coefficient using R
Hi.
I have data which i would want to assess the degree of agreement
between two assays, e.g., to evaluate reproducibility or for
inter-rater reliability. I have used the Pearson product-moment
correlation coefficient. It looks good ranginging between 0.90 to
0.998. Though this looks good. I am told the Concordance correlation
coefficient will give a better picture of how reproducible the assay

Concordance Index - interpretation
Hello everyone.
This is a question regarding generation of the concordance index (c
index) in R using the function rcorr.cens. In particular about
interpretation of its direction and form of the 'predictor'.
One of the arguments is a "numeric predictor variable" ( presumably
this is just a *single* predictor variable). Say this variable takes
numeric values.... Am I

lme model: Error in MEEM
Hi,
We have data of two groups of subjects: 32 elderly, 14 young adults. for
each subject we have 15 observations, each observation consisting of a
reaction-time measure (RT) and an activation maesure (betadlpcv).
since we want to analyze the influence of (age-)group and RT on the
activation, we call:
lme(betadlpcv ~ RT*group, data=our.data, random=~ RT |subject)
this yields:

Who can help me?
I have own function wrote. I used an algorithm, which was written in Matlab.
in matlab:
...
gamma = inv(v)*g;
...
#v = matrix of variable size, v=vv(k) => k=2 => dimension of v 2x2
#g = a line vector with 4 elements e.g. g=[1,0,2,0];
my rewritten r-file:
...
gamma = solve(v)*g;
...
which is my error? Who can help me?
thank you in advance.
