Longitudinal categorical response data
Dear List,
I have some longitudinal data, each patient was followed at times 0, 12, 16, 24 weeks and measure severity of a illness (0-worse, 1-same, 2-better). So, longitudinal response is categorical. I was wondering whether lmer in R can fit a model for this type of data. If so, how we code? Or any other function in R that can fit this type of longitudinal data? Any suggestion would be

Whitespace in img src
Hello,
markdown (Python implementation) seems to render:
![alternativer text](pfad/und/eine lange/url zum bild.jpg)
to
<img src="pfad/und/eine" title="lange/url zum bild.jpg"
alt="alternativer text"/>
breaking the URL at the whitespace. AFAIK whitespaces are ok in URLs
so why is it breaking up the URL here?
Thanks,
Florian

grant windows group share permission
Hello
i like to give a windows group (W2K3-AD) permissions to use a share
read/write on a Samba domain member server. Therefore if have added
the Samba server to the domain without problem and created a share
like this:

comment = Some Comment
path = /data/bild
admin users = root
force user = smbuser

Sweave: include a multi-page-pdf plot
Hi,
I'm just starting out with Sweave, and I can't get a plot(linmod) to
display all four plots:
<< bild >>=
x1 <- runif(100)
x2 <- rexp(100)
y <- 3 + 4*x1 + 5*x2 + rnorm(100)
mod <- lm(y~x1+x2)
plot(mod)
@

<<fig=TRUE>>=

This plots only the first image of the four-page plot.lm() result.

[follow-up] "Longitudinal" with binary covariates and outcome
Hi again!
Following up my previous posting below (to which no response

of question in a longitudinal modelling context.

simulate binary markov chain
Hi all, I was hoping somebody may know of a function for simulating a
large binary sequence (length >10 million) using a (1st order) markov
model with known (2x2) transition matrix. It needs to be reasonably
fast. I have tried the following;
mc<-function(sq,P){
s<-c()
x<-row.names(P)
n<-length(sq)
p1<-sum(sq)/n
s[1] <- rbinom(1,1,p1);
for ( i in 2:n){
s[i]

What is my replication unit? Lmer for binary longitudinal data with blocks and two treaments.
First I would like to say thank you for taking the time to read it.Here is my
problem.
I am running a lmer analysis for binary longitudinal (repeated measures)
data.
Basically, I manipulated fruits and vegetation to two levels each(present
and absent) and I am trying to access how these factors affect mice foraging
behavior. The design consist of 12 plots, divided in 3 blocks. So each

R: R: Hidden Markov Models
Thank you for your prompt answer.
The breathing signal observations are the amplitude values as a function of time and phase.
According to our model the hidden states are the different breathing types.
Subjects, whose respiratiion process is regular, are likely to breathe, keeping the same cycle pattern/type,
for many consecutive cycles. therefore dwelling in the same hidden state.

system() under windows [x] but not with Mac
Hey Guys,
i am kind of confused. Under windows the system() function works great, but
not with my mac.
I have two questions:
1) What do i have to change. Using packages which require system or
eval(parse() everything is fine, but
when i try it myself "sh: cmd: command not found"
Under windows i use e.g system('cmd /c copy "bild.jpg"',intern=FALSE )

fitting Markov Switching Model
Dear Users,
i have this time series, the tree lines means different level, i would use
a Markov switching model with two states to modelling this time series. i
would obtain the relative transition matrix (2X2)
the first state is above the value of 23.65 (the higher line)
the second state is below the value of 23.65
You can ignore the other two lines

"Longitudinal" with binary covariates and outcome
Hi Folks,
I'd be grateful for suggestions about approaching the
following kind of data. I'm not sure what general class of
models it is best situated in (that's just my ignorance),
and in particular if anyone could point me to case studies
associated with an R approach that would be most useful.
Suppose I have data of the following kind. Each "subject"

Markov Switching with TVTP - problems with convergence
Greetings fellow R entusiasts!
We have some problems converting a computer routine written initially for
Gauss to estimate a Markov Regime Switching analysis with Time Varying
Transition Probability. The source code in Gauss is here:

markov regime switching models
Hi,
I am looking for a package to estimate regime switching models (states
following a markov chain).
I found packages for Hidden Markov Models but I am looking for something a
little different: In the HMM the conditional distribution of the
observations (give the state) is a known distribution (normal or others),
while the package I need should allow to set a conditional distribution

Estimation of AR(1) Model with Markov Switching
Dear R users,
I have been trying to obtain the MLE of the following model

state 1: y_t = 0.5 + 0.9 * y_{t-1} + e_t
where e_t ~ iidN(0,1)
transition probability between states is 0.2

msm
Hello,
I'm writing about msm. It may be that consistent users of Markov models have a good idea as to what constitutes workable data for a model. I think of general rules, in basic statistical studies where n is limited to exclude fairly precise figures in the lower range.
On the other hand Markov models don't seem to be often enough used for parameters to be as well laid out.
I also
