Exception in NeweyWest - Pre-Whitening necessary?
Hi guyz,
I have run my algorithm in R (see http://pastebin.com/q84Tujfg) and got the following error:
Error in ar.ols(x, aic = aic, order.max = order.max, na.action = na.action, :
'order.max' must be < 'n.used'
I am pretty sure, that the error comes from the NeweyWest function in line 45, as the NeweyWest function uses the ar.ols() function for pre whitening. Does anyone

Whitening Time Series
Hi R users,
I am doing cross correlation analysis on 2 time series (call them y-series
and x-series) where I need the use the model developed on the x-series to
prewhiten the yseries.. Can someone point me to a function/filter in R that
would allow me to do that?
Thanks in advance for any help!

How to do a backward calculation for each record in a dataset
Hi Experts,
I have a dataset of 3 columns:
customer.name product cost
John Toothpaste 30

And I have a function of cost whereby
cost = 3.40 + (1.20 * no.of.orders^2)
I want to do a backward calculation for each records (each customer) to
find his no.of.orders and create a new column named "no.of.orders" in that

Partial whitening of time series?
I have a time series with a one year lag, ar=0.5. The series has some
interesting events that disappear when the series is whitened (i.e.,
fitting an AR process and looking at the residuals). I'd like to remove
the autocorrelation in stages to see the effect on the time series. Is
there a way to specify the autocorrelation term while fitting an AR
process?
For instance, given the following:

Analyze Fmri package
Hi,
Can you please help me?
Whenever I try to run f.ica.fmri.gui(), R crashes.
In the GUI, I selected an *.img file and I checked the 'Create mask' box and
I typed a name for the object and then I press 'Start' button. Then in the
R Console window it said 'Reading...Whitening', but after the Whitening
message an error window popped up and then R crashed.

transform() on selective names. Is it possible?
Hi all,
I am whitening my data:

some success with linux 2.6 and wcfxo
Hi ,
I picked up a x100p the other day and thaught I'd havea go at getting the
driver going for linux 2.6, things have gone pretty, two basic problems.
1. makefiles, with 2.6 you can't get away with using the old makefile to build
the kernel modules, they will build but you'll get an error along the lines of
"no module found in object". This is due to not using the new

Stupid passwd tricks: User with blank GECOS can''t change passwd
I have discovered that a user who has a blank GECOS field in the passwd file
under RedHat 4.0 (Colgate) is unable to change passwords. Running the passwd
command goes like this:
[user@host user]$ passwd
Password: [entry of old passwd]
New password: [entry of new passwd]
[user@host user]$ echo $!

[user@host user]$
Setting the name field in the GECOS seems to solve this problem.

auto.arima and intervention analysis
Hello,
I'm currently using auto.arima to verify the order of my arima model. I
would like to use the model to conduct an intervention analysis. The problem
is that, when I include a step function in auto.arima, by including a binary
variable in "xreg", the arima order that auto.arima gives is different from
when I don't include it. From my understanding, the
