interpreting an LME regression result...
Any help would be most appreciated. (Don't make me get down on my
hands and knees and beg for help, cause I'll do it!!) My boss has me
learning R and doing nested regression with the report due Mon (Friday
night statistics...fun. ). Anyway, here's my problem:
In a regression equation not accounting for the fact that people are
nested in families, the result for Z variable is VERY

How not to use AJAX
Hi all,
Just ran across this article
http://blog.taragana.com/index.php/archive/how-not-to-use-ajax/
and was curious what the consensus is on the bookmarking and search
indexing problems. I remember seeing something about bookmarking on the
list. Thanks,

SSD drives are really fast running Dovecot
I just replaced my drives for Dovecot using Maildir format with a pair
of Solid State Drives (SSD) in a raid 0 configuration. It's really
really fast. Kind of expensive but it's like getting 20x the speed for
20x the price. I think the big gain is in the 0 seek time.
Here's what I bought.

p-values from bootstrap - what am I not understanding?
Dear stats experts:
Me and my little brain must be missing something regarding bootstrapping. I
understand how to get a 95%CI and how to hypothesis test using bootstrapping
(e.g., reject or not the null). However, I'd also like to get a p-value from
it, and to me this seems simple, but it seems no-one does what I would like
to do to get a p-value, which suggests I'm not understanding

how to fix coefficients in regression
Hello all,
I am using a glm() and would like to fix one of the regression coefficients
to be a particular value and see what happens to the fit of the model. E.g.:
mod1 <- glm(Y ~ X1 + X2,family='binomial')
mod2 <- glm(Y~[fixed to 1.3]X1 + X2,family='binomial')
The beta for X1 is freely estimated in mod1 but is constrained to be 1.3 in
mod2. Is there a way to do this?

modeling variance heterogeneity in lme4
Hi all,
I have major heterogeneity in variances across labs (100-fold). There is no
apparent variance heterogeneity across y-hat. By using lme4 in the following
way, am I accounting for the variance differences in labs?:
lmer(y ~ fixed1 + covariates + (fixed1|labs))
I'm not sure that it is - I think it is only allowing the means (slopes
[conditional means] & intercepts) to differ

[PATCH v3 0/3] libxl: memory management patches
Hi,
Here are three small but important libxl/xl memory management patches:
- libxl: xl mem-max et consortes must update static-max in xenstore too,
- xl: Allow user to configure xl mem-set behavior,
- xl: Improve xl documentation in regards to guest memory management.

what does it mean when my main effect 'disappears' when using lme4?
Hello,
Setup: I have data with ~10K observations. Observations come from 16
different laboratories (labs). I am interested in how a continuous factor,
X, affects my dependent variable, Y, but there are big differences in the
variance and mean across labs.
I run this model, which controls for mean but not variance differences
between the labs:
lm(Y ~ X + as.factor(labs)).
The effect of X is

trouble with read.table and colClasses='raw'
Hi all,
First off, it is surprising that there are no examples of how to use
read.table() under ?read.table !
I am trying to read in a flat file of type 'raw'. It has 1000 rows and 600K
columns. I have the RAM to accomplish this, but can't get the data into R
using read.table:
x <- read.table("data",header=TRUE,colClasses=rep(,600000))

multiple separators in sep argument for read.table?
Hello,
Is there any way to add multiple separators in the sep= argument in
read.table? I would like to be able to create different columns if I see a
white space OR a "/".
Thanks in advance,

reading in table with different number of elements in each row
HI all,
This is probably simple, but I haven't been able to locate the answer either
in the Import Manual or from searching the listserve.
I have tab-delimited data with different numbers of elements in each row. I
want to read it into R, such that R fills in "NA" in elements that have no
data. How do I accomplish this?
Example:
DATA on disk:
1 -0.068191 -0.050729

Rollback to running VM
I would like to make a snapshot of a running VM, let it continue to run after the shapshot, and then at some later time roll back the VM to that previous running state. Can I do that with libvirt? If so, how? I understand that this will cause all kinds of havoc with things like ongoing TCP connections, and I accept that risk.

variables in templates
Here''s the problem I''m trying to solve.
I use apache, for lots of things, some of those things are configured from a
performance standpoint differently.
In less vague terms I need to be able to change the MaxClients setting to
different things based on the different purposes apache serves. (say proxy
vs. app)
Under previous CMS/templating engines I would have a httpd.conf that

Thanks.
IMO this patch should be considered for backporting, too.

Thanks for the info about the binary builds; I did install it, however the bug still seems to be there in the current build. The workaround you suggested does work:
