Assign statistically relevant groups following multimodal distribution of data
Dear R mailing list members,
?
I am trying to find a way to assign samples into groups depending on their mathematical distribution in a computational way (that is, looped many times). My input is by row, a series of 34 samples per row with n rows. The goal would be to compute the distribution of row n and assign for that row n the samples into bins that would match the distribution of the given

multinomial estimation output stat question - not R question
I am estimating a multinomial model with two quantitative predictors, X1
and X2, and 3 responses. The responses are called neutral, positive and
negative with neutral being the baseline. There are actually many models
being estimated because I estimate the model over time and also for
various parameter sets but that's not important. When I estimate a
model, since neutral is the baseline

Unexpected results using the oneway_test in the coin package
Dear fellow R users,
Keywords: Kruskal-Wallis, Post-Hoc, pair-wise comparisons, Nemenyi-Damico-Wolfe-Dunn test, coin package, oneway_test
I am using the "oneway_test" function in the R package "coin" and I am obtaining results which I cannot believe are accurate. I do not wish to waste anyone's time and so if the following problem is rather trivial, I apologize, however I

Check value interval in a if loop
Hi R community
I have a little problem, and I tried to solve it by myself but I couldn't. I building an if loop, and I want to check a value inside an interval. This would be the case:
pvalue=0,2999
if(pvalue>0.05 or pvalue<0.1)
as you can see I would like to check in that if loop if my pvalue is inside of that interval(from 0.05 to 0.1), and I tried these options:
if(pvalue>0.05

multi-comparison of means
Hi all:
I have a question about multi-comparison.
The data is in the attachment.
My purpose:
Compare the predicted means of the 3 methods(a,b,c) pairwisely.
I have 3 ideas:
#idea1
result_aov<-aov(y~ method + x1 + x2)
TukeyHSD(result_aov)
diff lwr upr p adj
b-a 0.845 0.5861098 1.1038902 0.0000001
c-a 0.790 0.5311098 1.0488902 0.0000002

Example (actual list has ~200 elements):

> temp2<- data.frame(ID=c("Herb","Shrub",

Matrices given to pt? [was: [R] for loops and counters]
Hi, people.
I was a bit intrigued by the message quoted below. Indeed, if pt() is
given a matrix, it returns a matrix. Should this feature be documented?
?pt speaks about "a vector of quantiles", and says nothing about the
type of what it returns.
The same might presumably apply to other distribution-related functions.

for loops and counters
I am trying to assign values to a vector (pvalue). Similar code works in C
but not in R. What am I doing wrong?
r <- pvalue <- 0
for(i in (1:(k-1))){
for(j in (i+1):k){
r <- r+1
tstat <- (means[i]-means[j])/rms
pvalue[r] <- 2*(1-pt(abs(tstat),df))
}
}
Thank you.

combined dependent pvalue
Dear All,
I am trying to combine dependent p-values in R. May you please help me with
this?
For independent pvalue combination, one of the popular way is fisher's
method which I found the R code here
(http://r.789695.n4.nabble.com/fisher-s-posthock-test-or-fisher-s-combination-test-td2195964.html#a2305025):

interprete wilcox.test results
Dear All,
I am using wilcox.test to test two samples, data_a and data_b, earch sample has 3 replicates, suppose data_a and data_b are 20*3 matrix. Then I used the following to test the null hypothesis (they are from same distribution.):
wilcox.test(x=data_a, y=data_b, alternative="g")
I got pvalue = 1.90806170863311e-09.
When I switched data_a and data_b by doing the following:
