VAR with GARCH effect
Dear list,
Can one suggest me if there is an R function/package to estimate and
simulate vector autoregressive (VAR) model allowing for the GARCH effect
please?
Thanks

plots for presentation
Dear users,
I am preparing a presentation in latex(beamer) . I would like to show parts
of my plots per click. Example, consider I have two time series x and y:
x<-ts(rnorm(100), start=1900,end=1999)
y<-ts(rnorm(100), start=1900,end=1999)
plot(x)
lines(y,col=2)
Then I imported this plot into latex as ".eps" file. My question is, how
can i show plot of each time series separately

A question about cointegration - How can we find the standard deviation in the cointegration relationship ?
Hello,
I am using urca package to run cointegration. I would like to find the
standard error in the (normalized, Johansen) cointegration relationship. How
can I do it?
As far as I know, The function "cajorls" in the "urca" package provides
the normalized cointegrating relationships. Nevertheless, it does not
provide the standard deviation of the coefficient for each

S+Finmetrics cointegration functions
Dear all,
S+Finmetrics has a number of very specilised functions. I am
particularly interested in the estimation of cointegrated VARs (chapter
12 of Zivot and Wang). In this context the functions coint() and
VECM() stand out. I looked at package "dse1", but found no comparable
functionality. Are there any other packages you could point me to? In
general, are there efforts for

VECM simulation
Dear members,
I estimated a vector error correction model (VECM) using the "ca.jo"
function in package "urca". I need to simulate the estimated model using R.
I am aware how to simulate a VAR(p) model. Since the VECM is
in difference form, I can't modify the VAR simulation codes to VECM. May
one help me in this regard please?
Thanks

cointegrating regression
Hi all,
Can I run a cointegrating regression, for example
delta Xt=a1(Yt-1-cXt-1)+E1t
and
delta Yt=-b1(Yt-1-cXt-1)+E2t
with R were
Xt and Yt are non stationary time series at t
a,b,c are parameters and E1t and E2t are error terms at t.
Yt-Xt is stationary
Any suggestions are welcome.
Best regards,

Cointegration Test in R
Hello!
I'm using the blrtest() function in the urca package
to test cointegration relationships.
Unfortunately, the hypothesis (restrictions on beta)
specifies the same restriction on all cointegration vectors.
Is there any possibility to specify different restrictions on
the cointegration vectors?
Are there any other packages in R using cointegration tests?
Thanks and best regards.

Cointegration and ECM in Package {urca}
Dear R Core Team,
I am using package {urca} to do cointegration and estimate ECM model,
but I have the following two problems:
(1) I use ca.jo() to do cointegration first and can get the
cointegration rank, alpha and beta. The next step is to test some
restrictions on beta with blrtest(),bh5lrtest(), and bh6lrtest(). But
none of them can add restrictions on all the cointegration

panel cointegration
Hi - i am looking for a package with which I can perform panel cointegration
tests. Old threads suggest plm and urca package, but I don't find suitable
tests in these packs. Somebody knows more?
best regards, Philipp

Cointegration Vectors
Hi,
I am trying to test the cointegration among 5 time series, grouped in pairs. I would like to save in a table the cointegration vectors for the 10 tests.
I used the urca package, but I dont know how to extract the data only for the cointegration vector.
Thanks in advance for help !

cointegration test
Dear All,
I am looking for a cointegration relationship between Spot and Future Price
of commodites. The problem i am facing follows:
1. After estimating by Engle-Grranger Method, i found that the residuals are
stationary at their level I (o), which is required to fulfill the
cointegration test. But the autocorrelation problem arises, as DW statistics
is signficantly low 0.50-0.88 for various

online classes or online eduction in statistics? esp. time series analysis and cointegration?
Hi all,
I am looking for low cost online education in statistics. I am thinking of
taking online classes on time series analysis and cointegration, etc.
Of course, if there are free video lectures, that would be great. However I
couldn't find any free video lectures at upper-undergraduate and graduate
level which formally going through the whole timeseries education... That's

Cointegration no constant
Hi,
I am trying to estimate a VECM without constant using the following code:
data(finland)

sjf.reg<-ca.jo(sjf, type = c("eigen"), ecdet = c("none"), K = 2,spec=c("transitory"), season = NULL, dumvar = NULL)
cajools(sjf.reg)
While the cointegration test does not use a constant, it is used in the cajools which I do not want. I am sure I am

Standard Error for Cointegration Results
Dear Sir/Madam,
I have used ca.jo in urca package to identify the cointegration and cajorls to estimate the vecm. Althought both return the coefficients for long run relationship (or ect1 in cajorls), I am unable to find the standard error and t statistics.
I spend some weeks to search around. I did find some similar enquiries before and answer provided Prof. Pfaff is to use vec2var. However,

Question regarding Johansen's cointegration testing
Hi,
I have a couple of questions about johansen's test, in general:
1. I was able to obtain error correction term (ect) from cajorls$rlm$model properly. According the my ca.jo object on 2-variate series, the test suggests that the integration rank is 1. Which means that my ect should be stationary. However, I did test stationariy on ect and it shows non-stationarity and my acf still shows

Question about testing cointegration using Autoregressive distributed Model (ADL)
Hi,I'm just wondering if there is any package for testing cointegration with ADL model. I saw a bunch of packages and list of email thread. There seemed to be no such a specific method. I am following this paper on how to test using ADL but I don't have a tool. http://www.wiwi.uni-frankfurt.de/~hassler/ha-wo.pdfAny help would be really appreciated. Thank you.Taco

Help with ca.jo and cajools (Johansen's Cointegration)
I am trying to run a conintegration analysis. I am a former user of S-Plus and understand the output of the coint and VECM output, but I am having trouble understanding the equivalent output in R.
Here is what I ran
