question of VECM restricted regression
Dear Colleague
I am trying to figure out how to use R to do OLS restricted VECM regression. However, there are some notation I cannot understand.
Please tell me what is 'ect', 'sd' and 'LRM.dl1 in the following practice:
#OLS retricted VECM regression

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

Default parameter values in R functions?
Hi all,
I have a newbie question:
If I have a function with the following documentation:
ca.jo(x, type = c("eigen", "trace"), ecdet = c("none", "const", "trend"), K = 2,
spec=c("longrun", "transitory"), season = NULL, dumvar = NULL)
Let's take "type" as an example... if I omit this parameter when

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?

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:

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

summary method in URCA package doesn't work
I can't figure out how to get the "summary" method in the URCA package to
work.
E.g. when I use the following code fragment in the help for the "ca.jo"
function,
it always tries to use the "summary" method from the "base" package,
not the "urca" package.
How do I force it use the "summary" method of the "urca" package?

VAR and VECM in multivariate time series
Hello to everyone!
I am working on my final year project about multivariate time series. There
are three variables in the multivariate time series model.
I have a few questions:
1. I used acf and pacf plot and find my variables are nonstationary. But in
adf.test() and pp.test(), the data are stationary. why?
2.I use VAR to get a model. y is the matrix of data set and I have made a

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

Five cases of the Multivariate VECM
Hello,
I was studying several packages related to time series analysis (urca,
vars, tseries). I understand that we can estimate a VECM and also test
restrictions on alphas and betas. However, I couldn't find a function that
allows me to specify the five cases of VECM (restricted constant,
unrestricted constant, restricted and unrestricted trend and no constant).
Is there any function that

cajolst
Dear R users,
I am quite new to R, so most of the problems I've encountered working with
it are technical, absurd or simple things. Sorry.
Despite this, I am struggling with cajolst function for a day and still
nothing. The problem is that I can't get an estimate for the break point
(which is in the slot "bpoint") by using cajolst function.
Finally, I've tried Johansen and

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

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().
