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 Mamush [[alternative HTML version

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 Emil -- View this message in

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")].

ca.jo
Dear R users; I'm using ca.jo for a VECM model. Is there a way that I can get sd/p-value to see whether coefficients estimated are statistical significant? Thank you Yours, Yihsu [[alternative HTML version deleted]]

How to run the VECM BEKK model in R?
Dear all, I want to run the VECM BEKK model, but I cannot find the corresponding package to run this model. Anybody can help?

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?

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.

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.

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

How to remove all objects except the sequence
Dear All: I would like to know if there is plausible way to say to R to remove all elements in the memory but the sequence. I have a code which makes a loop, and what I want is after the programme has performed all the operation over every "i"th element, to remove all the objects, expect the sequence parameter. I included the option "rm(list=ls(all=TRUE))", but obviously that

Help with ca.jo and cajools (Johansen's Cointegration)
I am trying to run a conintegration analysis. I am a former user of S-Plus and understand the output of the coint and VECM output, but I am having trouble understanding the equivalent output in R. Here is what I ran > coint=ca.jo(data,constant=T,K=2,spec="longrun") > summary(coint) The first portion of the output that I did not understand [,1] [,2] [,3] y1

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,

Function not found, maybe respective package has to be put in environment?
Hello everybody, I have a problem and would like to start with an example: library(snow) library(tseries) fn <- function(x) adf.test(x) clusterApply(cl=cl, x=x , fun=fn) R cannot find the function adf.test() because it is inside the function fn(). This problem does not occur when, for example, fn <- function(x) mean(x) holds. Therefore, I think the package tseries has to be put somehow

"Vars" package: impulse response function
Hello, I'm using VAR models in R in order to obtain impulse responses of stock market shock on US economy. I have series of quarterly changes in real gdp, S&P 500 and quarterly level of unemployment for 1985 - 2012 period. My series are stationary. So I did all the steps below. However I don't understand what do irf function results mean. These are the cumulative orthogonal responses

correlated events in time series
Apologies in advance for the basic nature of my question. I've never worked with time series, but I am, at present, dealing with evolution in time of certain scalar quantities. By looking at the plots, scalar quantity vs time, for several of these quantities, I am observing a correlation of "events" happening at specific, non-regularly spaced instants of time. The fact of observing

Vars package - specification of VAR
Hi useRs, Been estimating a VAR with two variables, using VAR() of the package "vars". Perhaps I am missing something, but how can I include the present time t variables, i.e. for the set of equations to be: x(t) = a1*y(t) + a2*y(t-1) + a3*x(t-1) + ... Y(t) = a1*x(t) + a2*x(t-1) + a3*y(t-1) + ... The types available in function VAR() allow for seasonal dummies, time trends and
