Error in minimizing an integrand using optim
...e itself is correct. Here's what am trying to do:
Minimize integration of a function of gaussian distributed variable 'x' over
the interval qnorm(0.999) to Inf by changing value of parameter 'mu'. mu is
the shift in mean of 'x'.
Code:
# x follows gaussian distribution
# fx2 to be minimized by changing values of mu
# integration to be done over the interval (qnorm(0.999),Inf)
p<-0.009 #constant
R<-0.25 # constant
e<-11 #constant
integrand<-function(x){
(e*pnorm((qnorm(p)+sqrt(R)*x)/sqrt(1-R))*dnorm(x))^2/dnorm(x+mu)}
fx2<-function(mu) {

?subexpressions, D, deriv
...comparison (so I cannot be 100% sure of my algebra).
What I would like is for the output of D to look at least somewhat
similar to my hand algebra. It occurred to me that if expressions
could be constructed from subexpressions, I could get a more
readable result (from D), as opposed to

-(invroot2pi/sigma) * (exp(-0.5 * (((x - mu)/sigma)^2)) * (0.5 *
(2 * (1/sigma * (1/sigma)))) - exp(-0.5 * (((x - mu)/sigma)^2)) *

So I tried, in the interests of simplification..

Displaying smooth bases - mgcv package
...a
thin plate regression spline in a gamm model. I've been searching the help
files, but I can't really figure out how to get the plots of the basis
functions. Anybody an idea?
Some toy code :
require(mgcv)
require(nlme)
x1 <- 1:1000
x2 <- runif(1000,10,500)
fx1 <- -4*sin(x1/50)
fx2 <- -10*(x2)^(1/4)
y <- 60+ fx1 + fx2 + rnorm(1000,0,5)
test <- gamm(y~s(x1)+s(x2))
plot(test$gam)
This gives me the conditional estimates, but not the basis functions for the
different splines. I'd like to have the basis functions for s(x1) and s(x2).
Cheers

arima() in package ts.
...ted directly from the residuals? How?
(Since the whole MLE structure is very complicated, I'm
pretty sure the answer is ``No it can't'', but I'd like
a little more insight into what's going on here.)
(3) I tried
x <- rnorm(100)
fx1 <- arima(x,c(1,0,0),c(1,0,0))
fx2 <- arima(x,c(2,0,0))
Note that seasonality is not specified and so defaults to 1.
I would have thought that the coeficients of the second
model, say phi.21 and phi.22, would be related to the coefficients
of the first (``multiplicative'') model, say phi.1 and Phi.1,
by
phi.21 = phi.1...

Using > summary(global.gamm4$mer), I get the following output for my spline

write list to ascii
Dear all,
apologies for this (perhaps recurrent) question but I did not found a question when searching mailing lists.
How to write a list of a simple kind, e.g.:

# to a file? I understand that write() & co. cannot work but when I try

Long running nbdkit tests
The nbdkit tests take a long time to run especially on armv7. To try
to get an idea of which tests take the most time, and since I happen
to have a qemu aarch64 *TCG* guest available, I ran the tests on that
guest.
A TCG guest is about the worst case for libguestfs, used by some
tests, since it uses double-nested TCG, and as you can see below there
are tests taking over 6 hours.

Low-memory Centos5?
Good morning,
I've inherited an old laptop from my wife that I'd like to
use when I travel (it's fairly small with a 12" screen). The
bad part is that it is maxed out on memory with 384MB.
Has anyone played with using Centos5 on systems with
little memory? Ideally, I don't need too much - Firefox,
Openoffice, a little Perl/Python/C here and there. I was

t.test in a loop
Hi All,
I've been having a little trouble with creating a loop that will run a a
series of t.tests for inspection,
Below is the code i've tried, and some checks i've looked at.
I've used the get(paste()) idea as i was told previously that the use of the
eval should try and be avoided.
I've run a single syntax to check that my systax is correct and works
without any problems

Rebuild of kernel 2.6.9-67.0.20.EL failure

I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without

Installed the kernel.scr.rpm and did a

The build failed at the end:
