Calculating the probability of an event at time "t" from a Cox model fit
Dear R-users,
I would like to determine the probability of event at specific time using
cox model fit. On the development sample data I am able to get the
probability of a event at time point(t).
I need probability score of a event at specific time, using scoring scoring
dataset which will have only covariates and not the response variables.
Here is the sample code:
n = 1000
beta1 = 2; beta2 =

reference classes, LAZY_DUPLICATE_OK, and external pointers
We (the lme4 authors) are having a problem with doing a proper deep
copy of a reference class object in recent versions of R-devel with
the LAZY_DUPLICATE_OK flag in src/main/bind.c enabled.
Apologies in advance for any improper terminology.
TL;DR Is there an elegant way to force non-lazy/deep copying in our
case? Is anyone else using reference classes with a field that is an
external pointer?

Seek some help on operating system drivers. Thanks!
Hello, I am a user of CentOS 7.6. I came here for help.
I recently bought a microserver called HPE Proliant MicroServer Gen10(X3216 APU).
CentOS 7.6 was installed for it. I found that the fan of the machine would keep turning and the noise was very loud. I searched everywhere but I couldn't find any way out.
Pardon my ignorance showing. I don?t know where to seek help.

Scoring using cox model: probability of survival before time t
Dear Members,
I required to score probability of survival before specified time using
fitted cox model on scoring dataset.
On the training sample data I am able to get the probability of a survival
before time point(t), but on the scoring dataset, which will have only
predictor information I am facing some issues. It would be great help for me
if you tell me where am I going wrong!

External MWI question for Asterisk
Hey there. I've been working on a project to integrate Asterisk with
Exchange Unified Messaging via sipX using large parts borrowed from:
http://blog.lithiumblue.com/2007/04/accessing-exchange-2007-unified_29.html
... and everything works surprisingly well. The one problem I have is MWI,
or a lack thereof. Exchange 2007 doesn't support MWI of any kind (!), so

Asterisk Manager and Visual Basic
Has anyone tried to used VB6 to communicate with the Asterisk Manager?
If so, would you be willing to share some basic code showing your
approach to getting connected and parsing results?
I've got a Telnet control that is allowing me to connect, authenticate
and see the "flow" of status, etc., but I'm sure there is a better way
to do this without using Telnet (maybe not?). Any

Asterisk 1.6 - Problems with SIP/REFER
I am having issues with transfers (SIP/REFER) using Asterisk 1.6. You will find the SIP debug below.

announcing an *early preview* of a cross-referencing code search website for LLVM
Hi,
I've found that one of the most useful tools in the Chromium project is its
code search website, http://cs.chromium.org/
At http://llvm-cs.pcc.me.uk/ you will find something similar for llvm. You
can search the full text of the llvm/clang/lld/lldb repositories using
regular expressions, search for declarations (which are prioritized above
full-text results), and follow cross references

Asterisk's DANGEROUS Transfer CDR's
Hi All,
PLEASE READ if you depend on Asterisk CDR's and support transfers.
Apologies for the shout but I'm desperate to get others to agree Asterisk has a
big problem with the CDR's that are generated for transfers. I can understand
why not too many people are interested as transfers are complicated and
messy. However for those of us having to support transfers and depending on

coxph() - unexpected result using Crawley's seedlings data (The R Book)
Hi,
I ran the example on pp. 799-800 from Machael Crawley's "The R Book" using package survival v. 2.36-5, R 2.13.0 and RStudio 0.94.83. The model is a Cox's Proportional Hazards model. The result was quite different compared to the R Book. I have compared my code to the code in the book but can not find any differences in the function call. My results are attached as well as a

Is GCC 2.95.2 also unusable?
Does anyone know if GCC 2.95.2 compiles a broken oggenc? My .ogg files

Instead, try:

pamer.fnc y la nueva versión de R
Javier,
Creo que aquí aplica la ley de Linus que dice: "Dado un número
suficientemente elevado de ojos, todos los errores se convierten en
obvios". La persona que revisa y encuentra un error no necesariamente
tiene que ser la misma que la que lo escribe. Una motivación muy importante
al compartir un código es la de recibir los beneficios del control de
calidad por parte de tus pares.
