Random factor ANOVA, Repeated measures ANOVA, Within subjects designs.
Hi,
we are just about to evaluate R as a standard statistics package for
our institute. We looked around the help - manual, the FAQ, etc. and
did not find anything for the topics of random factors in ANOVA,
repeated measures in ANOVA, or within subjects designs in R.
Could anyone point us to any information concerning

Wilcox Test / Mann Whitney U Test
Hello List,
I'm trying to prepare some lecture notes on non parametric methods,
and I can't manually reproduce the results of the wilcox.test function
for ordinal data.
The data I'm using are from David Howell's website, available here

If I run the wilcox.test function on the data I get a p-value of

Help with a more flexible funtion for multiple comparisio n of means
Jose -
Before implementing SNK and Duncan's, you may want to be aware of some
criticisms of these methods:
>From Hsu (1996),
"Newman-Keuls multiple range test is not a confident inequalities method and
cannot be recommended."
"Duncan's multiple range test is not a confident inequalities method and
cannot be recommended either. In the words of Tukey (1991),

Parametric tests
Hello,
I am interested in parametric multi comparison tests such as
Dunnett, Duncan, Tukey, Newman-Keuls, Bonferonni, Scheffe, and
non-parametric tests such as Kruskal-Wallis, and Mann-Whitney U. Are there
packages that include most of these tests in each category? Many packages
exist for an individual test but their outputs vary in great detail (test
statistics, p-values, etc.)

RT/Linux SCHED_RR/_FIXED to combat latency?
Good morning!
We're experiencing rather very bad latency spikes on busy Linux
systems, for example if one machine is the jumphost (ssh -J) for a few
hundred connections, while at the same time handles CPU intensive
tasks.
Would RT/Linux SCHED_FIXED or SCHED_RR be of help in such a case, e.g.
put all ssh processes into the SCHED_FIXED scheduling class, with a
priority higher than the

recommendation for post-hoc tests after anova
Greetings all,
I've done some ANOVAs and have found significant effects across my
groups, so now I have to do some post-hoc tests to ascertain which of
the groups is driving the significant effect. Usually one would do
something like a Newman-Keuls or Scheffe test to get at this but based
on googling and browsing through the r-help archives R doesn't support
these and they seem to be

ANOVA "ex post" Analysis
Hello everybody,
shame on me if I have overlooked something (CRAN, StatLib), but I think
I've searched carefully. Maybe it's just too obvious to see for me
(happens frequently).
Is a function available that extracts multiple comparison of means from
objects produced by "aov()" ? Sorry if the term is not correct, I

Evaluating a port to RTEMS (embedded OS with single address space and no processes)
Hello,
I am searching a SSH server for remote administration of an embedded
application running on RTEMS (https://www.rtems.org). This environment
has neither virtual memory nor user and kernel space. So this is like an
application running in kernel mode only.
Would it be possible to run (a very basic version of) OpenSSH in such an
environment using e.g. threads instead of forking new

multiple comparisons/tukey kramer
Hi,
I'm trying to make sense of the options for multiple comparisons
options in R. I've found the following options:
pairwise.t.test, which provides standard t-tests, with options for
choosing an appropriate correction for multiple comparisons
TukeyHSD, which provides the usual Tukey test

OpenSSH on Windows, ssh cannot |bind()| localport to port < 1023
Hi!
----
I'm doing some testing with the ssh client OpenSSH on Windows 10
(10.0-19045) but due to firewall restrictions I need to run my
experiments from a local port < 1024 (not negotiable).
I thought that this was no problem... but ssh |bind()| fails with
"address in use" (yes, I checked netstat, no one is there) for any
port < 1023.
Then I checked $ netstat # and $ netsh
