R function for computing Simultaneous confidence intervals for multinomial proportions
Dear all,
Does someone know an R function implementing the method of Sison and
Glaz (1995) (see full ref below) for computing Simultaneous confidence
intervals for multinomial proportions?
As alternative method, I think to boostrap the mean of each proportion
and get in that way confidence interval of the mean.
I observed 21 times a response that could be one out of 8 categories

Base R wilcox.test gives incorrect answers, has been fixed in DescTools, solution can likely be ported to Base R
While using the Hodges Lehmann Mean in DescTools (DescTools::HodgesLehmann),
I found that it generated incorrect answers (see
<https://github.com/AndriSignorell/DescTools/issues/97>
https://github.com/AndriSignorell/DescTools/issues/97). The error is driven
by the existence of tied values forcing wilcox.test in Base R to switch to
an approximate algorithm that returns incorrect results - see

multinomial confidence interval
Hi R users!
Is there a function that extracts the simultaneous confidence intervals for multinomial proportions as described by Sison and Glaz 1995? or anyone else for that matter?
I have seen that SAS has macro for this ( http://www.jstatsoft.org/v05/i06) and i was wondering if R had something similar?
Thank you and have a great day ahead!

How to test the difference between paired correlations?
Hello,
I have three numerical variables and I would like to test if their
correlation is significantly different.
I have seen that there is a package that "Test the difference between
two (paired or unpaired) correlations".
[https://www.personality-project.org/r/html/paired.r.html]
However, there is the need to convert the correlations to "z scores
using the Fisher r-z

DescTools::Quantile
It looks like a homework assignment. It also looks like you didn't read the documentation carefully enough. The 'len.out' argument in seq is solely for specifying the length of a sequence. The 'quantile' function omputes the empirical quantile of raw data in the vector 'x' at cumulative probabilit(y)(ies) given in the weights' argument, with interpolation I'm

Errors in wilcox family functions
Hi Everyone,
Following the previous discussion on optimizing *wilcox functions, Andreas Loeffler brought to my attention a few other bugs in `wilcox` family functions. It seems like these issues have been discussed online in the past few months, but I haven?t seen discussion on R-devel...unless I missed an email, it seems like discussion never made it to the mailing list. I haven?t seen any bug

Transform plot3d grafics in to executable files
Hello,
I did some nice grafics using plot 3d and scatter3d. Is there a,
hopefully not too complicated way, to transform these dynamic,
three-dimensional and interactive grafics in a kind of
executable file? I want to show and send them via e-mail to projekt
partners who don`t use GNU R and who are not used to do programming.
So the result should be quite comfortable to execute for them in

How to test the difference between paired correlations?
Thank you, but this now sounds more difficult: what would be the point
in having these ready-made functions if I have to do it manually?
Anyway, How would I implement the last part?

dynamic reports with sweave: error when compiling the tex-file
Hello,
I took my first steps in dynamic reports with Gnu R and used sweave().
I therefore run Sweave() with an example of Friedrich Leisch, starting
like this:
\ documentclass [ a4paper ]{ article }
\ title { Sweave Example 1}
\ author { Friedrich Leisch }
\ begin { document }
\ maketitle
and so on.
It worked very well but when I tried to compile the latex file I get

Printing output together
Hi!
I want to print the output all together with a single column name
s21<-c(1:1000);
var21<-lapply(s21,function(x){
ns<-rnorm(78,8,9);
n<-length(ns);
Mn<-mean(ns)
Sn2<-var(ns)
return(cbind(x,Mn,Sn2));
});

but my code is giving me somewhat like the following
[[1]] x Mn Sn2
[1,] 1 7.86 10.56540

Generating Hotelling's T squared statistic with hclust
I am doing a cluster analysis with hclust. I want to get hclust to output the Hotelling's T squared statistic for each cluster so I can evaluate is data points should be in a cluster or not. My research to answer this question has been unsuccessful. Does anyone know how to get hclust to output the Hotelling's T squared statistic for each cluster?

Heteroscedasticity and mgcv.
I have a two part question one about statistical theory and the other
about implementations in R. Thank you for all help in advance.
(1) Am I correct in understanding that Heteroscedasticity is a problem for
Generalized Additive Models as it is for standard linear models? I am
asking particularly about the GAMs as implemented in the mgcv package.
Based upon my online search it seems that some

Rounding multinomial proportions
I present you with a function that solves a problem that has bugged me for
many years. I think the problem may be general enough to at least consider
adding this function, or a revamped version of it, to the 'stats' package,
with the other multinomial functions reside.
I'm using R to export data to text files, which are input data for an
external model written in C++. Parts of the

dynamic reports with sweave: error when compiling the tex-file
Definitely yes I just tried a one line latex document and it bombed with \begin{ document } but is fine with \begin{document} .
I think the spaces within the {} must all be removed. Latex does not like spaces

how to make sip uri work
Lets say I have an * at my business, with 7960 SIP phones. All the sip
phones are registered using their extension number (like 305), but I would
also like to put my SIP URI on my business card and in a name format, not an
extension number (like lee.goodman), so that the SIP URI would read
lee.goodman@asterisk.company.com.
How would I set this up in extensions.conf?

Goodman / Kruskal gamma
The Goodman/Kruskal gamma is a nice descriptive rank-order
correlation statistic, often used in psychology. It is nice
because it is easy to understand. It takes all pairs of values
of each variable and asks whether they are congruent (S+ is the
number in the same order for both variables) or discordant (S-,
opposite ranking). The statistic is (S+ - S-)/(S+ + S-). It is
like tau except for the
