cut in R
Dear All,
I wonder whether it is still valid to use the following R code for cut. All I have done is changed:
if (is.na(breaks) | breaks < 2)
to:
if (is.na(breaks) | breaks < 1)
so that it covers interval of 1?
It seems okay for my purposes but I am not sure why R specifically does not allow break<2 to happen.
Steve.

How to hold a value(Mean sq) with a string
Hi all:
Can someone advice me on how to hold the residuals
Mean sq value on a string
so it can be used in other calculations.
I was trying something like this:
Msquare<-dfr$Mean sq but fails..Thanks

Initial values of the parameters of a garch-Model
Dear all,
I'm using R 2.8.1 under Windows Vista on a dual core 2,4 GhZ with 4 GB
of RAM.
I'm trying to reproduce a result out of "Analysis of Financial Time
Series" by Ruey Tsay.
In R I'm using the fGarch library.

[Re: Significance of confidence intervals in the Non-Linear Least Squares Program.]
Thanks for the response. I was not very clear in my original request.
What I am asking is if in a non-linear estimation problem using nls(),
as the condition number of the Hessian matrix becomes larger, will the
t-values of one or more of the parameters being estimated in general
become smaller in absolute value -- that is, are low t-values a
sign of an ill-conditioned Hessian?

instrumental variables regression using ivreg (AER) or tsls (sem)
Dear friends,
I am trying to understand and implement instrumental variables
regression using R.
I found a small (simple) example here which purportedly illustrates the
mechanics (using 2-stage least-squares):

Basically, here are the R commands (reproducible example) from that

How to Estimate Covariance by Week based on a linear regression model
Hi all:
I have always used SPSS to estimate weekly
covariance based on a linear regression model
but have to hard code the model Std. Error and the
Mean-Square and then execute
one week a the time. I was wondering if someone
could give me an idea on how to estimate
weekly(WK) covariance using the summary and anova of
"dfr"(lineal model below). I have

Set axis limits in mixtools plot
Hello,
Can the x and y axis limits be specified in a density plot with the
mixtools package for a finite mixture model? Uncommenting the xlim2/
ylim2 lines in the plot command below generates 'not a graphical
parameter' warnings (and does not change the axis settings), and
uncommenting the xlim/ylim lines generates a 'formal argument "ylim"

Hi Jack, thanks for the numbers. Any chance of analysing why gcc does better on
those where it does much better than dragonegg?
Ciao, Duncan.

contrast matrix for aov
How do we specify a contrast interaction matrix for an ANOVA model?
We have a two-factor, repeated measures design, with
Cue Direction (2) x Brain Hemisphere(2)
Each of these has 2 levels, 'left' and 'right', so it's a simple 2x2 design
matrix. We have 8 subjects in each cell (a balanced design) and we want to
specify the interaction contrast so that:

[LLVMdev] [RFC] AArch64: Should we disable GlobalMerge?
Hi all,
I've started looking at the GlobalMerge pass, enabled by default on
ARM and AArch64. I think we should reconsider that, at least for
AArch64.
As is, the pass just merges all globals together, in groups of 4KB
(AArch64, 128B on ARM).
At the time it was enabled, the general thinking was "it's almost
free, it doesn't affect performance much, we might as well use it".

[PATCH net-next RFC 0/3] virtio-net: Conditionally enable tx interrupt
Hello all:
We free old transmitted packets in ndo_start_xmit() currently, so any
packet must be orphaned also there. This was used to reduce the overhead of
tx interrupt to achieve better performance. But this may not work for some
protocols such as TCP stream. TCP depends on the value of sk_wmem_alloc to
implement various optimization for small packets stream such as TCP small
queue and auto
