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 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 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

fractional cointegration
Dear folk,
I am stempting to estimate a vector error correction model using a
seemingly fractionally integrated multivariate time series. The
*fracdiff *package
provides tools to estimate degree of fractional integration. But

help me to:
1. test equality of two degrees of fractional integration, say d1=d2?
2. estimate a multivariate cointegrating error correction model,

cointegration rank
Dear R - helpers,
I am using the urca package to estimate cointegration relations, and I
would be really grateful if somebody could help me with this questions:
After estimating the unrestriced VAR with "ca.jo" I would like to impose
the rank restriction (for example rank = 1) and then obtain the
restricted estimate of PI to be utilized to estimate the VECM model.
Is it possible?

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

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

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 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 no constant
Hi,
I am trying to estimate a VECM without constant using the following code:

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,

Trace values in the function ca.jo()
Hi all R users,
I'm trying to replicate the same results that are given in a published
article after been granted
the same data that the authors use.
I'm having problems to determine the cointegration rank of my data set using
the Johnasen's trace test.
This trace test is already programmed in the package ur.ca and can be found
in the function
ca.jo().
After I run the ca.jo()

Boxplot graphic
Dear R-users!
I boxplotted some data. the class of the data is numeric. There are some
outliers and I would like to see their names in the graphic. So, instead
that the data points of the outliers are plotted as points, I would like to
have their names plotted.
First of, how can I give my data series (class numeric) names? Second, how
could I adjust the boxplot to see the names of the outliers

Dear All,
I am looking for a cointegration relationship between Spot and Future Price
