Multivariate ARMA Model
Hi R-Community,
so far I dealt with univariate processes and used the function "arima" to
estimate an ARMA(1,1)-model. For multivariate processes there are the
functions "estVARXar" and "estVARXls" from package "DSE". But how can I
estimate an VARMA(1,1)-model, or even better determine the orders and
estimate the parameters?
Much thanks in advance,

Varma models in the dse package
Hi,
I tried to run the VARMA model in the dse package. I specified a model:
> arma
A(L) =
1+0.244L1 0+0.05L1
0-0.325L1 1-0.234L1
B(L) =
1-0.277L1 0+0.211L1
0-0.206L1 1+0.238L1
and have a TSdata object:
> dfdata
output data:
Series 1 Series 2

but I get this warning message:

VARMA
Hi all,
I want to estimate parameters from a VARMA(p,q)-Modell.
The equations of the model or the model structures is given by:
Xt=beta1+beta2*Xt-1+beta3*Yt-1+epsilon1
Yt=beta4+beta5*Yt-1+espilon2
epsilon1 and espilon2 are white noise.
Xt is given by a vector of n elements e.g. (2, 4, 7, 9, …,n)’ and Yt is
given by a vector of n elements e.g. (4,9,12,17,…,n)’.

Defining time series objects
Hi All,
I am new to R, having used S-plus a number of years back.
I would like to set up a time series object for forecasting, with data
collected daily between 5th April 2001 and 16th September 2001.
Any help would be most appreciated as I have been unable to find any
suitable examples in the documentation.
Thanks,
Mark.

dse package problems
I am having problems with the package dse. I just installed R 2.2.1
and reinstalled all packages. I am running Windows XP Pro with all
updates.
Below there are two examples of error messages generated when trying
to execute some simple programs. The code was taken directly from the
package documentation.
Any help on this will be greatly appreciated.
Merry Christmas

Multivariate Time series
Dear R People:
Is there a library for Multivariate time series, please?
For some reason, I'm thinking that Dr. Paul Gilbert may have one?
R Version 1.6.2 (i've updated!) for Windows
Thanks so much!

Package DSE
Hi,
If I try to do this:
if(is.R()) data("eg1.DSE.data.diff", package="dse1")
model <- est.VARX.ls(eg1.DSE.data.diff)
(Page 14 - DSE Package Manual)
I obtain a Segment Violation.
I use R-1.3.0 and the last dse package version

Kalman Filter in Control situation.
I am looking for a Kalman filter that can handle a control input. I thought
that l.SS was suitable however, I can't get it to work, and wonder if I am
not using the right function. What I want is a Kalman filter that accepts
exogenous inputs where the input is found using the algebraic Ricatti
equation solution to a penalty function. If K is the gain matrix then the
exogenous input

Multivariate time series
Hello to everyone!
I have a question for you..I need to predict multivariate time series, for
example sales of 2 products related one to the other, having the 2 prices
like inputs..
Is there in R a function to do it? I saw dse package but I didn't find what
a I'm looking for..
Could anyone help me?
Thank you very much

dse VAR models
Hi,
Can anyone tell me how to construct a simple VAR(1) time series with two
variables using the dse package? I would like to end up with two time series
y_1t = \phi_11 y_1,t-1 + \phi_12 y_2,t-1 + e_1t
y_2t = \phi_21 y_1,t-1 + \phi_22 y_2,t-1 + e_2t
Best regards,
Sam.

dealing with package bundles (was RE: Gregmisc)
Given the confusions that some users have regarding package bundles, I'd
like to suggest some changes to how package bundles are handled.
My understanding is that a package bundle is essentially a convenient way to
distribute related packages, so that users can download/install them in one
shot. However, some users apparently get confused that one can do
install.packages("abundle")

Bug in versioned install (was: (fwd) R-1.7.0 : Problem with Downloading "dse") (PR#2827)
The reason dse won't install is because of the new versioned install
code. It assumes that it's dealing with a plain package, and doesn't
handle bundles properly.
Robert, could you look at that?
A workaround is as follows. After the install.packages call fails

Simulate ARX model.
I have obtained from transfer functions, the state space matrices for the following state space model.
x* = Ax + Bu
y = Cx + Du
I have A, B, C, and D, now I would like to take the exogenous inputs and simulate the data using the state space model. I know there is a simulate function in the package dse1, but I am unsure as to what type of TSmodel to create to put into it. Could anyone give me

Fwd: dse package - load failure
Hello,
Sorry a second time again,
Maybe I have to add that I'm running R under Windows 2000/XP, and
that the download works properly under 1.062 but not under 1.070.

dse package - load failure
Dear Paul,
Hello R Maintainers,
I'm for the first time here and I hope its the right place to give the
following information:
The contributed R-package "dse" fails to be loaded from the menu button(s).
The reason is that it contains 4 sub-packages, dse1, dse2 ..., so the
DESCRIPTION file cannot be found. - One has to load it manually! -
Try it ... - It is possible to correct this?
