Help on glm and optim
Dear all,
I'm trying to use the "optim" function to replicate the results from the "glm" using an example from the help page of "glm", but I could not get the "optim" function to work. Would you please point out where I did wrong? Thanks a lot.
The following is the code:

Extract values from a predict() result... how?
Hello,
silly question I suppose, but somehow I can't manage to extract the
probabilities from a glm.predict() result:

Named num [1:9] 0.00814 0.01877 0.025 0.02941 0.03563 ...
- attr(*, "names")= chr [1:9] "1" "2" "3" "4" ...

plotting profile likelihood curves
Hello,
I am trying to figure out how to plot the profile likelihood curve of a GLM
parameter with 95% pCI's on the same plot. The example I have been trying
with is below. The plots I am getting are not the likelihood curves that I
was expecting. The y-axis of the plots is tau and I would like that axis
to be the likelihood so that I have a curve that maxes at the parameter
estimate. I am

Second copy engine on GF116
Hello,
There's a long-standing bug on nouveau (this is a sample bug, but the
issue has been around for a while:
https://bugs.freedesktop.org/show_bug.cgi?id=85465) whereby we attempt
to use the second PCOPY engine on GF116, and it is sometimes does
nothing, despite mmio register 22500 saying that it's not disabled
(0x22500 == 0 for this user). In the bug you can see a dump from

Fixing corrupted ogg files
I have several corrupted ogg files; I believe they were created several
years ago with grip, and that the corruption is not disk corruption but
just something wrong with the encoder at the time. I would rather not
have to re-rip these discs.
The error I see with ogginfo is
Warning: Hole in data (18000 bytes) found at approximate offset

x tick labels - sparse?
Hi,
I'm stuck on creating a plot with x tick labels for every Nth tick
mark - how is that done? I don't see a simple solution to this in
help(plot) or help(par) and what I've tried is not working, eg, the
following does not work, although it seems intuitive to me that it
should work:
x <- seq(-100,1000,25)
y <- x * x
% find all the x values that are multiples of 100

Syntax in taking log to transfrom the data to fit Gaussian distribution
Hi,
I have a data set (weight) that does not follow the Gaussian (Normal)
distribution. However, I have to transform the data before applying the
Gaussian distribution. I used this syntax and used log(weight) as:
posJy.model<-glm(log(weight) ~ factor(pos),
family=gaussian(link='identity'), subset=Soil=="Jy"). This syntax COULD NOT
transform the data. But if I transform the

[LLVMdev] using GCC LTO files as a frontend to dragonegg?
Hello,
With GCC, it is possible to compile GIMPLE from an object file back to
assembly. With Dragonegg, it seems to be a NOP. (See below for a
comparison.)
This appears it could be a nice way to mix the strengths of GCC and
LLVM. If it worked.. Should it?
Thanks,

Query about TSRV
Hi All,
This question may not belong here, but I asked this on the
R-SIG-FINANCE list and so far have not got any reply, so was hoping
someone here may help.
I have a basic query about TSRV and was hoping you all can shed some
light on the issue.
I have 22500 records for each day. So if I take the slow frequency as
5 mins I can have 75 subgrids. An estimate of the 5-minute realized

Second copy engine on GF116
Hi Ilia,
Actually 0x90b8 is different than copy engine. I'm not very familiar
with it, but 0x90b8 is an engine for performing LZO decompression as
part of performing the copy. It has a variety of limitations (e.g.,
cannot handle blocklinear format), and was only in a few Fermi chips,
as I understand it.
It is probably easiest to just ignore it. You can distinguish this

HTB qdisc within HTB root qdisc

Im trying to setup HTB to allow me to shape traffic from two upstreams
