lme v. aov?
I am trying to understand better an analysis mean RT in various
conditions in a within subjects design with the overall mean RT /
subject as one of the factors. LME seems to be the right way to do
this. using something like m<- lme(rt~ a *b *subjectRT, random=
~1|subject) and then anova(m,type = "marginal"). My understanding is
that lme is an easy interface for dummy coding

SE of ANOVA (aov) with repeated measures and a bewtween-subject factor
Hallo!
I have data of the following design:
NSubj were measured at Baseline (visit 1) and at 3
following time points (visit 2, visit 3, visit 4).
There is or is not a treatment.
Most interesting is the question if there is a
difference in treatment between the results of visit 4
and baseline. (The other time points are also of
interest.) The level of significance is alpha=0.0179

repeated measures regression
How does one go about doing a repeated measure regression? The
documentation I have on it (Lorch & Myers 1990) says to use linear /
(subj x linear) to get your F. However, if I put subject into glm or
lm I can't get back a straight error term because it assumes
(rightly) that subject is a nominal predictor of some sort.
In looking at LME it seems like it just does the right thing

A repeated measures, linear mixed model (lme) WITHOUT random effects...
Hello,
I am trying to fit a repeated measures linear mixed model (using lme)
but I don't want to include any random effects. I'm having trouble (even
after consulting Pinheiro & Bates 2000) figuring out how to specify the
repeated measure without including it in the specification of a random
effect.
My data consist of repeated "counts" in "plots" that I wish

help repeated measures factoial design
Dear All,
A few weeks ago I posted a question to this list but unfortunately got no
answer! A friend warned me of my english.
Again, the problem is:
A 2-level 5-factors completely randomized design was used to investigate the
potential effects of those factors on a solution's characters (several response
variables).
Each response-variable was measured repeatedly (13 times) during a

does lme repeated measures require sphericity?
I haven't been able to find an answer on this that's direct, only
implied. In several places I have read that when people asked for
sphericity tests they were guided toward lme or mlm models. But,
there is no direct indication that the lme method is not subject to
the sphericity assumption. In fact, it seems like it should be. Its
just a linear model that handles random and

[PATCH 1/1] vhost_task: Fix vhost_task_create return value
vhost_task_create is supposed to return the vhost_task or NULL on
failure. This fixes it to return the correct value when the allocation
of the struct fails.
Fixes: 77feab3c4156 ("vhost_task: Allow vhost layer to use copy_process") # mainline only

GLM->Repeated measures (multivariate)
Dear subscribers,
I'm trying to make the switch from M$ Windows to Linux (KDE) and found the
R-cran project for statistical analysis. I'm not a genius in statistics so
the command line interface is a bit hard for me.
I need an analogue way to do the SPSS General Linear Model->Repeated

[PATCH v2 0/7] vhost-scsi: Fix crashes and management op hangs
The following patches were made over Linus tree. The patches fix 3
issues:
1. If a user performs LIO LUN unmapping before the endpoint has been
cleared then we can end up trying to free a bogus tmf struct if the
TMF is still exucuting when we do the unmap.
2. If vhost_scsi_setup_vq_cmds fails we can leave the tpg->vhost_scsi
pointer set and we can end up trying to access a freed struct.

[PATCH 0/5] vhost-scsi: Fix management operation hangs
The following patches were made over Linus tree and also apply over
mst tree's vhost branch. The patches fix an issue where management
operations like LUN mapping/unmapping and device addition hang for 30
seconds or up to N minutes depending on the device.
The problem is that we use a global mutex to protect the list of tpgs
but we hold that mutex during those management operations. So if you

Repeated Measures Analysis - GLM
Hello to the R world...
I have some problems regarding a GLM - repeated measures analysis.
I want to test overall differences between AgeClass and Treatment (between
subject) with OpenR1+OpenR2+OpenR3 (repeated measures, within subject). The
table looks kind like this:
AgeClass Treatment OpenR1 OpenR2 OpenR3

1 1 12.67 3.83 45.67

[PATCH 1/3] signal: Don't always put SIGKILL in shared_pending
When get_pending detects the task has been marked to be killed we try to
clean up the SIGKLL by doing a sigdelset and recalc_sigpending, but we
still leave it in shared_pending. If the signal is being short circuit
delivered there is no need to put in shared_pending so this adds a check
in complete_signal.
