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

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

Hi,
is somebody out there who has successfullly built R-065 on SuSE-6.2
Linux ?
This is for short, If nobody has I?ll describe the problem in depth
later.

Understanding of Johansen test.
Dear all,
I am struggling to understand the johansen test procedure in the context of co-integration in time series. Yes I understand that this forum is not directly statistics related but still I am posting here hoping that I would get som help.
The error correction representation of a VAR[p] model can be written as:
Delta y[t] = A[0]*y[t-1] + A[1]*Delta y[t-1] +..............

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

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

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

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,

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 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

When upgrading from source, it's ok to just run make install and every files will be overwritten with the new version?
Nothing else one should do?

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

How to obtain cointegrated relationship from ca.jo in urca package?
Hi,
I can plot the ca.jo package to view the cointegrated relationship for each eigen value. Or I can use the normalized eigen vector to reconstruct the cointegrated relationship series. However, since the package can plot that for me, I wonder is there any specific slot/method in the class from where I can invoke to get this relationship instead of doing a duplicated work? Thank you.
