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

sjd <- denmark[, c("LRM", "LRY", "IBO", "IDE")]

the significance of BEKK estimation
Dear ALL,
I use BEKK package to estimate Bivariate GARCH model. But when the results
come out, there's no t-stat or p-value of the estimated coeffients. Does
anyone know how to get the significance?
Followings are the codes I input,
>P1=data.frame(x,y)
>y1=mvBEKK.est(P1)
>mvBEKK.diag(y1)
Anyhelp would be appreciated!
Sincere,
Zoe

About multivariate GARCH: DVEC and BEKK
Dear All,
I attempted to fit a DVEC and a BEKK multivariate GARCH model, but am
wondering which package to use.
1. I tried to use "rmgarch" package in R, but I couldn't find the
subroutines for DVEC and BEKK.
2. I tried to find "rmgarch" package of R, which is not located on the
official R site. This is the latest version I can find, where the programs

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

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

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

VECM with UNRESTRICTED TREND
Dear All,
My question is:
how can I estimate VECM system with "unrestricted trend" (aka "case 5")
option as a deterministic term?
As far as I know, ca.jo in urca package allows for "restricted trend"
only [vecm
<- ca.jo(data, type = "trace"/"eigen", ecdet = "trend", K = n, spec =
"transitory"/"longrun")].

mgarch-BEKK
Dear all..
Can anybody help me with mgarchBEKK? After estimate bekk model, i want to
check whether the residuals meet the required assumptions. Can i perform
Portmanteau test, the ARCH-LM test, plots of the AC and PAC functions of the
residuals? Can you give some example with the script in R? Please..
Thank You So Much

Issues related to jruby 1.0.2/edge rails and rspec head
Hi,
We just spent half an afternoon figuring out why "jruby -S rake spec" didn''t
generate any output at all (no warnings) on an edge rails app. We were
seeing different behaviour on different boxes, and after a while figured out
that it was related to a missing diff-lcs gem on one box.

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:
