Standard Error for Cointegration Results
...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, I still can't find corresponding info. after using vec2var function. Highly appreciate if someone could advise by using a step by step with codes. For example, in the paper of ""VAR, SVAR and SVEC Models: Implementation Within R Package vars", how to get the t-statistic...

VAR and VECM in multivariate time series
...I get estimation of AIC in this model?
3. I also get a VECM model
v1=VECM(y, lag=16,beta=NULL, estim="ML")
what does ETC mean in the output?
and what is a number of cointegrating relationships?
I want to make forecast by VECM.
j=ca.jo(y,K=16,type='trace',season = NULL)
j.var=vec2var(j)
predict(j.var,n.ahead=80)
Is this a correct way to predict VECM in R?
Could anyone help me?
Thank you very much

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,

Trying to extract an algorithm from a function
Hi, I'm using package "vars" and I'm trying to extract the algorithm that
function "predict" contained in that package in order to understand how does
it work.
When I type function "VAR" then all its algorithm appears in R, however if I
try to do the same with "predict" nothing happens...Is there any possible
way to extract the algorithm?
Thanks 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

Simulating a VEC
Hello everyone,
I have estimated a VEC using functions of package urca. Now I need to
simulate several trajectories of the variables of the model based in the
information of the model. To do that first I converted the VEC to a VAR
using vec2var (from package vars) and then I converted de VAR to an ARMA
using ARMA function of package dse. The idea is to use the function simulate
(from package dse), to simulate the ARMA from the VEC using the initial
values of the variables of the model, the exogenous variables in the
simulation period and...
