grangertest/lmtest ... what am I doing wrong ?
Dear Achim, R Users,
What am I doing wrong in this example ?
a<-zoo(rnorm(100),order.by=1:100)
b<-lag(a)
regr<-na.exclude(merge(a,b))
plot(regr)
grangertest(regr[,1],regr[,2],3)

MSBVAR Package
dear sirs or madam,
As I'm interested to search about the monetary transmission channel in our
country by MSVAR model, I would be grateful if you help me and tell me how
can I run MSVAR in R or send me the related code to run this model .
Actually, I'm new user of R and I don't know how to run Markov Switching
Var Model in R.
Thank you very much in advance for your help.

"invest" applet in centos 5.1 seems to be inoperative
Hello!
I figured it'd be interesting to see a miniature graph of the Dow Jones
on my panel bar. Unfortunately, it doesn't appear to do anything, and
the preferences for it isn't helpful (it already has DJIA).
So, any suggestions on how to get it to work?

calculate impulse responses
Dear R users,
I need perform structural analysis on a no intercept VAR model. Unfortunately the functions irf.VAR and dfev that come with the MSBVAR package only work with objects output by the reduced.form.var function, which seems to only evaluate VAR models with intercept. Is there a way to suppress the estimation of intercept term in reduced.form.var? Do I need to modify the code, and if I

Need help to estimate the Coef matrices in mAr
Dear R users,
I am using mAr package to fit a Vector autoregressive model to my data. But
here I want to put some predetermined values for some elements in
coefficient matrix that mAr.est going to estimate. For example if p=3 then I
want to put A3[1,3] = 0 and keep rest of the elements of coefficient
matrices to be determined by mAr.est.
Can anyone please tell me how can I do that?
Sincerely

Multivariate time-series
Hi all,
I'm looking for R packages that estimate multivariate time-series models
or vector-autoregression (VAR) time-series models.
Thanks

Converting the results of granger.test into a matrix
Dear R Users,
The granger.test command in the MSBVAR package estimates all possible
bivariate Granger causality tests for m variables. If one passes a data
frame with 3 rows, it returns 6 granger tests in two rows, one for the
F-statistic and another for the p-value.
For example:
> a<-rnorm(1:10)
> b<-c(lag(a),rnorm(1))
> c<-c(lag(b),rnorm(1))

MSBVAR and hc.forecast
attempting to do multivariate modelling in R with known future
conditions (in this case variable 'b') using MSBVAR and hc.forecast.
The sample code (a paired down representation) does not give anywhere
near the expected results - I am assuming that a forecast 8 steps out
would approximate 'a' as the sequence 1.1,2.1,3.1,100.1 corresponding
to the input set.

Interpret impulse response functions from irf in MSBVAR library
Hello,
I am wondering if anyone knows how to interpret the values returned by irf
function in the MSBVAR library. Some of the literature I have read indicates
that impulse responses in the dependent variables are often based on a 1
unit change in the independent variable, but other sources suggest that they
are based on a a change of 1 standard deviation. Any ideas which irf uses to
compute the

Cisco ISE unable to retrieve AD group list from samba 4 server
Hi all,
I have run into a problem with our samba4 setup. I have successfully
joined a Cisco ISE v1.1.4 (Identity Service Engine) test machine to the
samba4 AD. User authentication does work but unfortunately the ISE is
unable to fetch the AD groups from the domain controller. In the samba
logs I get the following error message when initiating the group fetch:

Tuýrkish Character Set

I am new to this list. I have (and all Trukish users of Samba) trouble with
Turkish charactes (iso8859-9)with Samba. I saw some character definition tables
in charcnv.o (in sources). I couldn't understand the logic. A part of the table
for iso8859-2 is

We are planning to integrate CISCO-ISE with Samba-AD (Version 4.6.5).
Websense gateway / proxy are all properly integrated and even single

Cluster analysis, defining center seeds or number of clusters
I use kmeans to classify spectral events in high and low 1/3 octave bands:
#Do cluster analysis
CyclA<-data.frame(LlowA,LhghA)
CntrA<-matrix(c(0.9,0.8,0.8,0.75,0.65,0.65), nrow = 3, ncol=2, byrow=TRUE)
ClstA<-kmeans(CyclA,centers=CntrA,nstart=50,algorithm="MacQueen")
This works well when the actual data shows 1,2 or 3 groups that are not
"too close" in a cross plot.

The command VER is hazardous because it encourages exploiting of
implementation peculiarities that are not well documented in a
protocol.? The best example of such a failure is the browser version
field in HTTP.? A complete disaster.? You should warn against use of
this command, or even better, deprecate it.

Ferret 0.9.0-alpha (port of Apache Lucene to pure ruby)
Hi Folks,
I''ve just released version 0.9.0. This latest version of Ferret is an
alpha release. I have removed the old c extension and Ferret is now
running on a fully ported C library. This has allowed some huge
performance improvements both with regard to memory and CPU usage.
There will probably be a few portability issues to start with. It has
been developed on Linux so it should
