an ordinal regression MCMC run high correlation
I am trying to model a clusterd ordinal response data (either 1, 2 or 3) called , the correponding physician of the patient is also in the data.
Since it is ordinal, I used the ordinal logit model
topbox[i]~discrete with probability P[j,1],p[j,2], p[j,3], j is the corresponding physician of the ith patient
C[j] is the physician effect , a1 and a1+theta is the common cutpoints for all

R2WinBUGS sending variables as factors
Hello R and BUGS users,
I am writing a heirarchical model in R to send to BUGS via R2WinBUGS and
I am finding it difficult to get the model to run. I seem to be having
two problems.
1) I can't seem to send variables classed as factors (Month), is there a
way do this?
2) Checking the Log in WinBUGS I can see that the model is Syntactically
correct, but Bugs is not able to recognise the the

Selective Survival Statistics with R
Hello friends and fellow R users,
I have a problem to which I have been unable to find a solution: I am
gathering survival data on patients undergoing treatment with a new kind
of stent. I want to generate survival data and plot survival curves of
these patients based (among other things) on the treating physician. My
data set has been tabulated in the following manner:

Clustering Question
Hi group,
My case has N physicians with each seeing M patients.
One physician could have seen a group of patients, or,
a patient could have been seen by multiple number of
physicians. In order words, there are overlaps. Now,
I have the following NxM matrix
Patient#1 Patient#2 Patient#3 .......
Patient#m
Physician#1 1 0 1 .......

A question about R2Winbugs
Dear R users:
I was trying to fit a HMM with mixture of Gaussian into the dataset, and I
tried to implement it by R2Winbugs. But I got the following errer.
*
Error in FUN(X[[1L]], ...) :
.C(..): 'type' must be "real" for this format*
Does anybody know what's the problem? Does R2Winbugs accept some matrix as
inits? I would really appreciate your help. Thank you very much.

gamm with correlation structure question
Dear group,
I am trying to use gamm() in mgcv. Here's the
scenario. The data frame has approx. 110K
observations with information on paediatric
readmission binary outcome (Y/N) and total volume of
their most responsible physician as the covariate.
Since any physician can have multiple patients, the
data contains clustering structure which I am trying
to account for. My original formula is

Input on application design
I have an online doctor/dentist search. Right now I have all the code
in one controller, with separate views and actions for the doctor and
dentist. About 80% of the code in both the controller and the view is
shared. Doctors and dentists are in separate tables with different
(yet very similiar) schema''s. So the sql queries are different, and
some of the information displayed in the

MCMC for sampling from ordinal logistic regression
Hi:
Is there a R-function that can generate samples from the posterior distribution of an ordered logistic regression model (just like MCMCoprobit from MCMCpack in R). I will greatly appreciate some guidance in this regard.
Thanks

Intermittently Get "Target filesystem does not support long file names" when copying file to Samba share
I have two CentOS servers running samba3-3.0.34-37. When I connect to a

to it, I often get the message "target filesystem does not support long
filenames." Sometimes it works and sometimes it doesn't. I've been

What if my Windows AD Domain Controller Goes Down?
There are three DCs in my Windows 2003 AD domain, but I have noticed
that only one of them is referenced in my krb.conf and krb5.conf. Should
there be a reference to one or two of the other domain controllers? If
the DC goes down, how will my Samba/Winbind servers authenticate?

Difference between summary.lm() and summary.aov()
I have a simple linear model (fitted with lm()) with 2
independant
variables : one categorical and one integer.
When I run summary.lm() on this model, I get a
standard linear
regression summary (in which one categorical variable
has to be
converted into many indicator variables) which looks
like :
Estimate Std. Error t value Pr(>|t|)

Backslash Escaping in View
Ok, I''m hoping this won''t be a forehead slapper, but take a look at this code:

Intermittently Get "Target filesystem does not supportlong file names" when copying file to Samba share

Glad to hear it. That's the kind of behavior I would normally expect.
One thing that might be different between our environments is that my
users are all in Remote Desktop sessions connected to a pair of Windows
terminal servers.

Long Pause the First Time I Do an 'ls' on Linux.
We have a lot of users on our AD domain, and the more we add the longer
it takes to get a directory listing on my Linux servers. When I do 'ls
-l' it might take 20 seconds before the listing starts. However, if I
immediately do 'ls -l' again, it comes up quickly. I assume this is
because samba/winbind is polling the AD domain controller on the first
attempt. Is there any way to

Linux Servers in an AD Domain with Multiple Windows Domain Controllers
We have three Windows domain controllers in our AD domain. They are DC01, DC02, and DC03. We have Linux (RHEL5 and 6) servers in the domain as well. The Linux servers are working fine with AD. However, they are currently configured in krb.conf and krb5.conf to use only DC01 for AD domain controller. if DC01 is down, Linux servers cannot authenticate. How do we configure the Linux servers to use

How to Configure Samba to Use Multiple AD Logon Servers for Redundancy
Our samba boxes are integrated with our Windows 2003 AD domain, with
Windows servers acting as AD domain controllers. Everything is working
fine, but in my krb.conf and krb5.conf files on my Linux boxes, I
currently only have one Windows server specified as the AD logon server.
If that server is down, I suspect that Linux users could not login. How

Samba running but stops working? Then no work after restart?
Greetings,
I have a FreeBSD 3.1 and Samba 2.0.5a box doing domain logons and file sharing

encountered something very interesting. Win9x boxes can no longer login. So ,
I examine the problem and it appears that things are ok but none of the things
samba is supposed to be doing is happening. Again this box serves many

How to detect if the call is being answered by Voice Mail?
Hi,
I am pretty new to Asterisk. I am trying to make sure some human being
answers the phone not the voice mail machine. How can I programmatically
identify that?
Here is my Sub:
sub DialPhysician {
my ($self, $con, $PhysicianPhone, $call_id, $conv_id) = (@_);
to_log($self, "Inside Dial Physician", 2);
my $DocPhone = "1".
