Question about Johansen result
Hi,I obtained the ect term from cajorls in urca. I found a result that would like to obtain some explanation here. My setting is that I have 2 variate time series. I use ca.jo to perform Johansen test. 1. I found that sometimes, in the case where the ca.jo test statistics suggest that I have 1 relationship. After I investigate the ect obtained from cajorls (with r=1), the ect series fails unit

Fitting VAR and doing Johansen's cointegration test in R
Hi,
Could someone please tell me the R codes for fitting VAR(p) (Vector
Auto Regressive) models and doing the Johansen?s cointegration tests.

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

cointegration analysis
Hello,
I tried to use urca package (R) for cointegration analysis. The data
matrix to be investigated for cointegration contains 8 columns
(variables). Both procedures, Phillips & Ouliaris test and Johansen's
procedures give errors ("error in evaluating the argument 'object' in
selecting a method for function 'summary'" respectiv "too many

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,

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

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
> coint=ca.jo(data,constant=T,K=2,spec="longrun")
> summary(coint)

Cointegration/urca package
Hello!
I estimate vector error correction model (vecm) model. I have only one cointegratio relationship. I write :

standard errors in johansen test
Dear all,
I have a question. How to get the standard errors of alpha and beta
when using "ca.jo" to test cointergration?
In the paper by Bernhard Pfaff and Kronberg im Taunus “VAR, SVAR and SVEC
Models: Implementation Within R Package” pp.24-25. The standard errors are
listed on the table 5 following the code:
R> vecm.r1 <- cajorls(vecm, r = 1)

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

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

Interper output from cajorls and VECM
Hi all R users,
I'm finding it a bit hard to interpret the output from the cajorls and VECM
function. I'm trying to model a VECM model with cointegration rank of 6, and
therefore I get the varibles ECT1, ECT2... ECT6 in my output. Are these
representing the estimates for my loading matrix or also denoted the "alpha"
matrix?
Thanks in advanced

Package update: 'urca' version 0.3-3
Dear R-list member,
an update of package 'urca' has been uploaded to CRAN (Mirror: Austria).
In the updated release unit root and cointegration tests encountered in
applied econometric analysis are implemented. The package is written in
'pure' R and utilises S4 classes.
In particular, the Johansen procedure with likelihood ratio tests for the
inclusion of a linear trend,

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

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.

Question regarding panel data diagnostic
Good day R-listers,
I'm currently working on a panel data analysis (N=17, T=5), in order
to check for the spurious regression problem, i have to ?test for
stationarity but i've read somewhere ?that i needn't to test for it as

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 !

Regression output labels
Hello to all-
1. When I run a regression which implements the augmented Dickey-Fuller
test, I am confused about the names given to the regressors in the output.
I understand what "xGE" stands for in a standard "lm" test involving an
independent variable GE for instance, but if I lags and or differences are
included in the model, what do the following "output" stand
