Heteroscedasticity Plots
...ernet tutorials in R do not agree what
is the best plot for detecting heteroscedasticity. What do you use?
I found so far:
- Y vs X
- Res vs X
- Res vs Fitted Y
- Partial regression plot
and lots of standardized/studentized/partial plots.
Thank you very much in advance!

Adjusted R-squared formula in lm()
...viously thought, and read widely, that R-squared penalizes for adding additional variables to the model. Now the use of these different formulas seems to call for different interpretations?
My two questions in short: Which formula is used by R lm()? How can I interpret it?
Thank you!

equalize / ecmp not working as expected in 2.6 vs 2.4
Hi,
With kernel 2.4 I was able to use equalize to send our outgoing packets to
two different routers (our isp supports this setup), like this:
ip route add default src ip.a.dd.rr equalize nexthop via <router1> weight 1
nexthop via <router2> weight 1
The two routes were used equally on a per packet basis, not per flow or per
cached route, but per packet, each line has 800k upload

htb traffic shaping problem
Hello.
I have a linux server connected to a gigabit lan, and though that lan to a
768kbps/768kbps DSL modem.
I''m trying to shape my webserver running on port 80/443 down to 512kbps,
while leaving all other ports alone. The current configuration script that
I''m using is as follows:
tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1: htb default 99
tc class add dev

syslinux vs isolinux - com32 serial port output problem
...s expected. The only difference appears to be the missing output on COM2 when booting from a CD. Yes, I have tried this using different CD drives. I have even tried this on a couple of different systems (a "final ship" and an open-frame "test fixture").
Any ideas?

The "ip route get" returns wrong interface and gateway in an multipath routing environment
...eway ( I did not test it on more
environments ). On an installed Ubuntu 6.06 LTS the behaviour is also
wrong ( I found this problem on a 2.6.15-28-server kernel with the same
iproute package ).
¿ Any idea why this is happening ? ¿ Is this a regression ? ¿ Any
suggestions ?
Kind Regards,
Eric Janz

vcovHC and arima() output
Dear all,
how can I use vcovHC() to get robust/corrected standard errors from an
arima() output?
I ran an arima model with AR(1) and got the estimate, se, zvalue and
p-value using coeftest(arima.output).
However, I cannot use vcovHC(arima.output) to get corrected standard
errors. It seems vcovHC works only with lm and plm objects?
Is there another way I can get robust/corrected

Re: htb traffic shaping problem (Charlie Meyer)
Eric,
I''ve attached the output from the command you requested below.
I''m using kernel 2.6.17.12 and tc version ss060323. I''m have a nforce4
onboard giggabit controller using the forcedeth driver, if that makes a
difference.
Charlie,
I''ll take a look at the Apache model for throttling, thanks. I was going

I''m using tc to limit the bandwidth of our wireless customers. I have a

syslinux vs isolinux - com32 serial port output problem
Hi Geert,
I'm building syslinux 6.04 from scratch to prevent any issues with mismatched com32 modules. This gives me a "pure" set of modules as well as "pure" isolinux and syslinux cores.
menu.c32 works perfectly on both the USB and CD boot media: I can move around the menu and select the command that I wish to use. In all cases, both the USB and CD boot properly into
