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

Errors in wilcox family functions
...- tied values in either one- or two-sample tests: these can force R to use a normal approximation even in low-sample cases.
- degenerate two-sample tests (`max(x)==min(x)` and `max(y)==min(y)`): this produces an error due to an unhandled edge case.
This particular issue has caused problems for the DescTools package, which recently reimplemented HodgesLehmann due to inaccurate results in base R. At the very least, warnings should probably be added so that users don?t misinterpret these results. Better still would be to just fix these cases, but I haven?t dug super deep into the codebase yet, so I?m no...

simultaneous confidence intervals for multinomial proportions: sample size
...ot;partially" and I expect that far more than 5 samples fall into each category.
I have read that Glaz & Sison's method is only appropriate for variables with 7 or more categories. Therefore, the Goodman method seems like a good idea.
I have found the R function "MultinomCI" {DescTools} to calculate these CIs.
However, I have not found a way to calculate in advance the required sample size for the Goodman method at a fixed confidence level and length of the intervall.
I would be very grateful for any suggestion.
Many thanks in advance!

How to test the difference between paired correlations?
...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 transform". I have seen that there is another
package that does that
[https://search.r-project.org/CRAN/refmans/DescTools/html/FisherZ.html].
Yet, I do not understand how to process the data. Shall I pass the raw
data or the correlations directly?
I have made the following working example:
```
# define data
v1 <- c(62.480, 59.492, 74.060, 88.519, 91.417, 53.907, 64.202, 62.426,

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?
