similar to: Added Variable Plot for Cox Regression

Hi, I'm using a Cox-Regression to estimate hazard rates on prepayments. I'm using the "pspline" function to face non-linearity, but I have no clue how to interpret the result. Unfortunately I did not find enough information on the "pspline" function wether in the survival package nor using google.. I got following output: * library(survival)* > > > >

Hi, I am just wondering if there is a test available for testing if a linear fit of an independent variable in a Cox regression is enough? Thanks for any suggestions. John Zhang ____________________________________________________________________________________ [[elided Yahoo spam]]

On examining non-linearity of Cox coefficients with penalized splines - I have not been able to dig up a completely clear description of the test performed in R or S-plus. >From the Therneau and Grambsch book (2000 - page 126) I gather that the test reported for "linear" has as its null hypothesis that the spline coefficient is the same at the center of basis. Thus, in the example

Suppose I have a dataset contain three variants, looks like > head(dta) Sex tumorsize Histology time status 0 1.5 2 12.1000 0 1 1.8 1 38.4000 0 ..................... Sex: 1 for male; 0 for female., two levels Histology: 1 for SqCC; 2 for High risk AC; 3 for low risk AC,

Hi all, Is there an equivalent to predict(...,type="linear") of a Proportional hazard model for a Cox model instead? For example, the Figure 13.12 in MASS (p384) is produced by: (aids.ps <- survreg(Surv(survtime + 0.9, status) ~ state + T.categ + pspline(age, df=6), data = Aidsp)) zz <- predict(aids.ps, data.frame(state = factor(rep("NSW", 83), levels =

Greetings - Does anybody know if there is an R implementation of the Wei-Lachin tests for incomplete multivariate observations (JASA 79: 653-661)? The authors' example of data where this test can be applied is in a study comparing treatment to placebo where the outcome is a series of time-to-event observations - i.e., time to development of a nonfatal symptom in each of several major

Hello all, I recently tried to install a webcam that I have through wine. When I ran the windows xp/2000/vista/win7 driver through wine, this was the output I saw in terminal Code: fixme:iphlpapi:NotifyAddrChange (Handle 0x8fee90c, overlapped 0x8fee8f0): stub wine: configuration in '/home/jarrod/.wine' has been updated. fixme:storage:create_storagefile Storage share mode not implemented.

Dear all, Let's assume I have a clinical trial with two treatments and a time to event outcome. I am trying to fit a Cox model with a time dependent treatment effect and then plot the predicted survival curve for one treatment (or both). library(survival) test <- list(time=runif(100,0,10),event=sample(0:1,100,replace=T),trmt=sample(0:1,100,replace=T)) model1 <- coxph(Surv(time,

Hi Everyone, I'm trying to load some C++ code using dyn.load but I'm getting unresolved symbols associated with some external libraries (CSparse). I gather this is something to do with linking as the the code compiles fine. However, I've passed -L/home/jarrod/My_Programs/SuiteSparse/CSparse/Lib -lcsparse to the complier (g++), either directly using R CMD SHLIB or as

For those that were interested I have attached the kamailio.cfg which we have working with Kamailio 4.2.1 and Asterisk 1.8.23/32. Specifically, the following yum packages: kamailio.x86_64 4.2.1-4.1 @home_kamailio_v4.2.x-rpms kamailio-auth-ephemeral.x86_64 4.2.1-4.1 @home_kamailio_v4.2.x-rpms kamailio-bdb.x86_64 4.2.1-4.1 @home_kamailio_v4.2.x-rpms

Hi, You should look at Pinheiro and Bates (2000) Mixed-effects models in S and S-Plus. It describes how to format the correlation matrix to pass to functions lme and gls. Basically, the correlation matrix has to be one of the corStruct classes, probably corSymm for your example. So in the call to lme (or gls if you really have no random effects), use something like:

Hi, I ran R (version 2.9.0) CMD build under root in Fedora (9). When it tried to remove "junk files" it removed EVERYTHING in my local account! (See below). Can anyone tell me what happened, and even more importantly if I can I restore what was lost. Panickingly, Jarrod [jarrod at localhost AManal]$ R CMD build MCMCglmm_2.05 * checking for file

Hi! I have a problem according to the logonHours setting in my Samba Domain. Users are in LDAP, and everyone has a logonHours attribute, which could be: - login is possible at any time - login is only possible between 7AM and 12PM(mindnight), 7h-24h in 24 hours format, I'm going to use 24h format here in this post. Samba manual states than logonHours is a 168 bit mask, starting with Sunday

Good afternoon, gentlemen! After several days studying and researching on categorical data (various forums with answers from the owner of the library - all incipient) how to interpret the output the function MCMCglmm, come to enlist the help of you, if someone has already worked with MCMCglmm function in the case of variables ordinal dependent. I've read and reread all the pdf's of the
