Package dlm version 0.8-1
I uploaded a new version of package dlm to CRAN. dlm provides functions for maximum likelihood, Kalman filtering and smoothing, and Bayesian analysis of Gaussian linear state space models, also known as Dynamic Linear Models. The most important visible changes from the previous version are the following. 1) Missing values are now allowed in the observations. 2) Extractor and replacement

Hyperparameters in ARIMA models with dlm package
Hi, i'm beginner in Bayesian methods, I'm reading the documentation about dlm package and kalman filters, I'm looking for a example of transformation of ARIMA in a state space equivalent to use the dlm package and calcualte the hyperparameters. Someone can help me about it?. If it's possible with a arima(1,0,1) example, or more complex model. While I have more examples best for me.

[PATCH 1/2] ocfs2/dlm: Make o2dlm domain join/leave messages KERN_NOTICE
o2dlm join and leave messages are more than informational as they are required is debugging locking issues. This patch changes them from KERN_INFO to KERN_NOTICE.

[PATCH] ocfs2/dlm: check dlm_state under spinlock
We should check dlm->dlm_state under dlm->spinlock though maybe in this case it doesn't hurt.

[PATCH 2/5] ocfs2/dlm: add lockres as parameter to dlm_new_lock()
Wether the dlm_lock needs to access lvb or not depends on dlm_lock_resource it belongs to. So a new parameter "struct dlm_lock_resource *res" is added to dlm_new_lock() so that we can know if we need to allocate lvb for the dlm_lock. And we have to make the lockres availale for calling dlm_new_lock(). Signed-off-by: Wengang Wang <wen.gang.wang at oracle.com> ---

Strange behaviour of `dlm` package
Dear R-help! I have encountered strange behaviour (that is, far-off filtering, smoothing and forecast distributions under certain conditions) in the `dlm` package by Giovanni Petris. Here is an example: I use the annual hotel bookings time series data, which I model using a second order polinomial DLM. First I perform the analysis with the data in logarithmic form and everything seems to be

DLM Problem?
Hello, I have an active, balanced webcluster with 2 SLES10SP2 nodes, both running ocfs2 with an iscsi target. The ocfs2 volume is mounted on both nodes. Everything works fine, except sometime the load on both systems go as high as 200, then both systems freeze, only reboot helps to regain control. I noticed that this behaviour does not occur when the cluster is NOT balanced. When the load on both

[PATCH 1/1] ocfs2 fix o2dlm dlm run purgelist
There are two problems in dlm_run_purgelist 1. If a lockres is found to be in use, dlm_run_purgelist keeps trying to purge the same lockres instead of trying the next lockres. 2. When a lockres is found unused, dlm_run_purgelist releases lockres spinlock before setting DLM_LOCK_RES_DROPPING_REF and calls dlm_purge_lockres. spinlock is reacquired but in this window lockres can get reused. This

Setting up a model in package dlm()
Hello, I apologize for such a basic question, but I have been trying to do this in multiple packages without much success. I am trying to set up a state space model for Kalman filtering. I am using package dlm. The DLM is specified by: observation: y(t) = F(t)*theta(t) + v(t) state: theta(t) = G(t)*theta(t-1) + w(t) I have no problem setting up a simple example where F is constant. I am

Tracking time-varying objects with the DLM package (dynamic linear models in R)
Hello all, I am working with the dlm package, specifcially doing a dlm multivariate Y linear regression using dlmModReg and dlmFilter and dlmSmooth... I have altereted the inputs into dlmModReg to make them time-varying using JFF, JW etc. How do I track the results of the time varying system matrices? For example what I am really interested in is JW - my system variance matrix for each time

Possible locking problem in DLM code
Hi, with lockdep enabled, I get the warning below. I've verified it and it seems to be really correct - we acquire dlm->ast_lock and lockres->spinlock in different orders in dlm_queue_bast() and dlm_lockres_release_asm(). I'm not sure whether this can really lead to a deadlock and / or how to fix this... Honza ======================================================= [

Where can I find formal document for DLM ?
Hi folks, After reading some google search result and wikipedia, finally I want to ask this question: Where can I find some formal document for DLM ? The only document I can find is HP's How the Distributed Lock Manager (DLM) Works. Is there any other document which people use as a spec to implement DLM ? If yes, could you please to give me the URL. Thanks in advance for any help :-) --

Help with kalman-filterd betas using the dlm package
Hi all R gurus out there, Im a kind of newbie to kalman-filters after some research I have found that the dlm package is the easiest to start with. So be patient if some of my questions are too basic. I would like to set up a beta estimation between an asset and a market index using a kalman-filter. Much littarture says it gives superior estimates compared to OLS estimates. So I would like to

Forecasting with dlm
Hi All, I have a problem trying to forecast using the dlm package, can anyone offer any advise? I setup my problem as follows, (following the manual as much as possible) data for example to run code CostUSD <- c(27.24031,32.97051, 38.72474, 22.78394, 28.58938, 49.85973, 42.93949, 35.92468) library(dlm) buildFun <- function(x) { dlmModPoly(1, dV = exp(x[1]), dW = exp(x[2])) } fit <-

[PATCH 1/4] ocfs2/dlm: Retract fix for race between purge and migrate
Mainline commit d4f7e650e55af6b235871126f747da88600e8040 attempts to delay the dlm_thread from sending the drop ref message if the lockres is being migrated. The problem is that we make the dlm_thread wait for the migration to complete. This causes a deadlock as dlm_thread also participates in the lockres migration process. A better fix for the original oss bugzilla#1012 is in testing.

Time invariant coefficients in a time varying coefficients model using dlm package
Dear R-users, I am trying to estimate a state space model of the form (1) b_t = G * b_t-1 + w_t w_t ~ N(0,W) (2) y_t= A' * x_t + H' * b_t + v_t v_t ~ N(0,V) (Hamilton 1984: 372) In particular my estimation in state space form looks like (3) a3_t = 1 * a3_t-1 + w_t w_t ~ N(0,W) (4) g_t = (a1, a2) * (1, P_t)' + u_t * a3_t + v_t v_t ~ N(0,V) where g_t is the
