re(4) problems with GA-H77N-WIFI
Hello,
I need some advice how to debug this issue ...
Recently I got a new mainboard for a router, it's a
Gigabyte GA-H77N-WIFI with two onboard re(4) NICs.
The problem is that re0 works fine and re1 doesn't:
It doesn't receive any packets. Tcpdump displays all
outgoing packets, but no incoming ones on re1.
Ifconfig shows the link correctly (100 or 1000 Mbit,

MCMCglmm with cross-classified random effects
Dear R-users,
I would like to fit a glmm with cross-classified random effects with
the function MCMCglmm. Something along the lines:
model1<-MCMCglmm(response~pred1, random=~re1+re2, data=data)
where re1 and re2 should be crossed random effects. I was wondering
whether you could tell me specifying cross-classified random effects
in MCMCglmm requires a particular syntax? Are there any

Unlist alternatives?
dfhfsdhf at ghghgr.com
I ran a simple lme model:
modelrandom=lmer(y~ (1|Test) + (1|strain), data=tempsub)
Extracted the BLUPs:
blups=ranef(modelrandom)[1]
Even wrote myself a nice .csv file....:
write.csv(ranef(modelrandom)[1],paste(x,"BLUPs.CSV"))
This all works great. I end up with a .csv file with the names of my strains
in the first column and the BLUP in the second

BLUP with missing data
hello guys, I need to do a BLUP in the simplest model
y = Xm + Zg + e
however I have missing data in the analysis which I can?t consider as
0(zero). So I need to generate the matrix X'Z, Z'X and Z'Z step by step; I
can?t use
crossprod(x) #neither
X'X <- t(x)%*%x
because I should skip the elements with missing data in the matrix
I?ll try to be more clear,

How to obtain prediction intervals for random effects?
Hello!
I wonder how can one get upper and lower limits of a prediction interval
-- exact values? They are shown on caterpillar plot using ranef() with
argument postVar=TRUE, but I would like to know them. A while ago, some
discussions were opened on "Confidence Intervals for Random Effect
BLUP's", but the answer was never clear:

Where the error message comes from?
Hi all:
I get the following error message that I am not able to resolve.
Error in if (const(t, min(1e-08, mean(t)/1e+06))) { :

It appears right before the last data.frame statement.

Scaling behavior ov bVar from lmer models
Hi all,
To follow up on an older thread, it was suggested that the following
would produce confidence intervals for the estimated BLUPs from a linear
mixed effect model:
OrthoFem<-Orthodont[Orthodont$Sex=="Female",]
fm1OrthF. <- lmer(distance~age+(age|Subject), data=OrthoFem)
fm1.s <- coef(fm1OrthF.)$Subject
fm1.s.var <- fm1OrthF. at bVar$Subject

lme, mixed models, and nuisance parameters
I have the following dataset:
96 plots
12 varieties
2 time points
The experiment is arranged as follows:
A single plot has two varieties tested on it.
With respect to time points, plots come in 3 kinds:
(1) varietyA, timepoint#1 vs. variety B, timepoint#1
(2) varietyA timepoint #2 vs. varietyB timepoint #2
(3) varietyA timepoint #1 vs. variety A timepoint#2
- there are 36 of each kind

extrating BLUP values from linear mixed models

I wish to learn how to extract best linear unbiased predictor values from a
linear mixed model of repeated measures on individuals which has a random error

Thanks for your time,
Kind regards

Intermittent failure
Hello.
I'm in need of some help to shed some light on a strange problem.
The box is running Samba 4.1.7 on FreeBSD 9.2/amd64 and I suspect
(though I'm not sure) all troubles started after the upgrade from 4.1.6.
The setup is quite simple: no AD, no LDAP, only one server.

[nlme] BLUPs for a new subject in a fitted lme model?
I am seeking for a method to calculate, given a fitted lme model
and some data for a subject, the random effects predictors
for this subject. I can only find predictors for the subjects used in
creating the fit. Of course I could just add the subject and redo the fit.
But I want to avoid just this refitting.
Thanks for help

Penalized Splines as BLUPs using lmer?
Dear R-list,
I?m trying to use the lmer of the lme4 package to fit a linear mixed model
of the form
Y = Xb + Zu + e
and I can?t figure out how to control the covariance structure of u. I want
u ~ N(0,sigma^2*I).
More precisely I?m trying to smooth a curve through data using the
"Penalized Splines as BLUPs" method as described in Ruppert, Wand &
Carroll (2003).
So I have Z = [Z1

emperical bayes estimates and standard error lme4
Dear all,
I am trying to get the emperical bayes estimates together with their
standard errors out of lme4. Up to now I have used MLwiN to get these
estimates. I have fitted the following - very simple - model, just to
find out how this works.

standardized random effects with ranef.lme()
Using ranef() (package nlme, version 3.1-75) with an 'lme' object I can
obtain random effects for intercept and slope of a certain level (say:
1) - this corresponds to (say level 1) "residuals" in MLWin. Maybe I'm
mistaken here, but the results are identical.
However, if I try to get the standardized random effects adding the

Routes
hi all,
I want to move some routing tasks out of the router and into the
controller. The goal is to make Merb feel less like mod_rewrite and
give the user more control at the controller. The new Router is
simple: it takes the path_info (not the whole request) then outputs a
controller class and some parameters from the path matching. The rest
of the routing would be done at the controller level.
