Multivariate Granger Causality Tests
Dear Community,
For my masters thesis I need to perform a multivariate granger causality
test. I have found a code for bivariate testing on this page
(http://www.econ.uiuc.edu/~econ472/granger.R.txt), which I think would not
be useful for the multivariate case. Does anybody know a code for a
multivariate granger causality test. Thank you in advance.
Best Regards

Automatically extract info from Granger causality output
Dear Community,
this is my first programming in R and I am stuck with a problem. I
have the following code which automatically calculates Granger
causalities from a variable, say e.g. "bs" as below, to all other
variables in the data frame:
log.returns<-as.data.frame( lapply(daten, function(x) diff(log(ts(x)))))
y1<-log.returns$bs
y2<- log.returns[,!(names(log.returns) %in%

Optimal lag selection in Granger Causality tests
Dear R Users,
Can someone point me to a R package which will help me optimally choose a
lag for Granger Causality testing ?
Many thanks in advance,

Wiener-Granger Causality Test in R
Hello dudes.
I'm developing VAR analysis based on suggestions made by Horváth in its
paper Canonical Correlation Analysis and Wiener-Granger Causality Tests.
That's the reason I'm looking for if there's any R package to develop Wiener
- Granger Causality Test.
Thanks a lot for your unvaluable help.

test for causality
Hi useRs..
I cant figure out how to test for causality using causality() in vars
package
I have two datasets (A, B) and i want to test if A (Granger)cause B.
How do I write the script? I dont understand ?causality. How do I get x to
"contain" A and B. Further using the command VAR() to specify x, I dont
either understand.
Kind regards Tobias

Modified Sims test
Does anyone know of a package that includes the Modified Sims test
[Gewerke, 1983, Sims, 1972]?
This test is used in econometrics and is a kind of alternative to the
Granger test [Granger, 1969], which is in the package lmtest.
Thanks in advance,
chris

Converting the results of granger.test into a matrix
Dear R Users,
The granger.test command in the MSBVAR package estimates all possible
bivariate Granger causality tests for m variables. If one passes a data
frame with 3 rows, it returns 6 granger tests in two rows, one for the
F-statistic and another for the p-value.
For example:
> a<-rnorm(1:10)
> b<-c(lag(a),rnorm(1))
> c<-c(lag(b),rnorm(1))

Granger causality with panel data (econometrics question)
Hi folks,
I am trying to perform a Granger causality analysis with panel data. There
are some packages around for panel data analysis and Granger causality.
However, I have found neither a package for both panel data and Granger
causality nor any R procedures (homogenous/heterogenous causality
hypotheses, related tests such as Wald, unit root tests etc.).
Of course, someone must have

Spectral Analysis of Time Series in R
Dear R Community,
I am currently student at the Vienna University of Technology writing my
Diploma thesis on causality in time series and doing some analyses of
time series in R. I have the following questions:
(1) Is there a function in R to estimate the PARTIAL spectral coherence
of a multivariate time series? If yes, how does this work? Is there an
test in R if the partial spectral

Quantile Regression - Testing for Non-causalities in quantiles
Dear all,
I am searching for a way to compute a test comparable to Chuang et al.
("Causality in Quantiles and Dynamic Stock
Return-Volume Relations"). The aim of this test is to check wheter the
coefficient of a quantile regression granger-causes Y in a quantile range. I
have nearly computed everything but I am searching for an estimator of the

Convergent Cross Mapping
Dear All,
I am looking for an R implementation of the convergent cross mapping
method (see http://bit.ly/XN8OZX and
http://www.uvm.edu/~cdanfort/csc-reading-group/sugihara-causality-science-2012.pdf
)
The method is presented as an improvement over Granger causality (
http://bit.ly/XN8ydi ), but its implementation (involving shadows of
multidimensional manifolds) must be quite some work...

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

VAR question
Hi all,
I got another VAR question here and really appreciate if somebody would help me out :)
I have five time series, say A,B,C,D,E. My objective is to predict the series A using the rest, that is, B, C, D and E. A Vector Autoregression Model should work here. But first of all, I should select which series of B, C, D and E to be include in the VAR model, as well as the number of lags. I wonder

Estimating a bivariate VAR(X) and using F-tests
I would like to estimate bivariate VAR(X) models where I don't know the
optimal lag length X and would also like to use
F-tests to determine the granger causality of each of the variables. I'm
aware of Achim's econometric packages description but I was wondering if
someone could recommend a specific R econometrics package that does
this.

What am I doing wrong in this example ?

Version 1.4.7 of package vars
Dear useRs,
The package vars, implementing multivariate time series models VAR and
VECM, has been updated to version 1.4.7
The new changes are:
-the compatibility with the sandwich/lmtest package, which allows to use
heteroskedasticity consistent (HC) covariance estimators, to do
inference on the parameters taking into account heteroskedasticity of
unknown form.
-Implementation of a
