Frailty and coxph
Does someone know the rules by which 'coxph' returns 'frail', the
predicted frailty terms? In my test function:
-----------------------------------------------
fr <- function(){
#testing(frailty terms in 'survival'
require(survival)
dat <- data.frame(exit = 1:6,
event = rep(1, 6),
x = rep(c(0, 1), 3),

coxme with frailty--variance of random effect?
Dear all,
This probably stems from my lack of understanding of the model, but I
do not understand the variance of the random effect reported in coxme.
Consider the following toy example:

library(survival)
library(coxme)
#--- Generate toy data:
d <- data.frame(id = c(1:100), #

coxph and frailty
Hi:
I have a few clarification questions about the elements returned by
the coxph function used in conjuction with a frailty term.
I create the following group variable:
group <- NULL
group[id<50] <- 1
group[id>=50 & id<100] <- 2
group[id>=100 & id<150] <- 3
group[id>=150 & id<200] <- 4
group[id>=200 & id<250] <- 5
group[id>=250

Variance of random effects: survreg()
I have the following questions about the variance of the random effects in the survreg() function in the survival package:
1) How can I extract the variance of the random effects after fitting a model?
For example:
set.seed(1007)
x <- runif(100)
m <- rnorm(10, mean = 1, sd =2)
mu <- rep(m, rep(10,10))
test1 <- data.frame(Time = qsurvreg(x, mean = mu, scale= 0.5, distribution =

Extracting parameters for Gamma Distribution
I'm doing a cox regression with frailty:
model <- coxph(Surv(Start,Stop,Terminated)~ X + frailty(id),table)
I understand that model$frail returns the group level frailty
terms. Does this mean this is the average of the frailty
values for the respective groups? Also, if I'm fitting it to
a gamma frailty, how do I extract the rate and scale
parameters for the different gamma

Survival analysis with COXPH
Dear all,
I would have some questions on the coxph function for survival analysis,
which I use with frailty terms.
My model is:
mdcox<-coxph(Surv(time,censor)~ gender + age + frailty(area, dist='gauss'),
data)
I have a very large proportion of censored observations.
- If I understand correctly, the function mdcox$frail will return the random
effect estimated for each group on the

chgrp work-around thingy
I have 2 user groups accessing documents in /export/docs: staff and exec.
I need to give users in the group 'staff' the ability to create folders
and documents in /export/docs.
On creation of (either) folders or documents in /export/docs, all items
should be owned by their respective creators AND users in the 'exec'
group; thus:
# ll /export/docs/

Verification on HOW adding a machines works
I'm straddling the half-way point between samba and ldap. When adding a
machine to the domain, functionally, it works like you would expect. You
enter in the domain, enter your credentials, and reboot. The computer is
able to function as a machine on the domain.
I'm using the smbldap-tools as suggested in the wiki. Here's the script:

frailtypack
I can't comment on frailtypack issues, but would like to mention that coxme will handle
nested models, contrary to the statement below that "frailtypack is perhaps the only ....
for nested survival data".
To reprise the original post's model
cgd.nfm <- coxme(Surv(Tstart, Tstop, Status) ~ Treatment + (1 | Center/ID), data=cgd.ag)

AIC from coxme
Hi,
I am running the following model:
fit1.full <- coxme(Surv(age_sym1, sym1) ~ sex + lifedxm*sex + (1|famid),
data=bip.surv)
I would like to extract the AIC from that object to calculate the AICC.
However, when I look at str(fit1.full) and summary(fit1.full) (pasted
below) I don't see anything that would allow me to get pull the AIC out
from that object.
Is there a way to retrieve the

Interfaz gráfica para docencia
Buenas noches,
tengo que hacer un curso introductorio de R para mis alumnos de Psicología. Algo muy básico que les ayude a trabajar con estadísticos sencillos.
Había pensado en darles R Comander. Me surge la duda de si existe alguna otra interfaz gráfica más novedosa o que pueda serme de más utilidad para mis intereses.
Muchas gracias de antemano.
Un saludo

How to interpret these results from a simple gamma-frailty model
Dear R users,
I'm trying to fit a gamma-frailty model on a simulated dataset, with 6 covariates, and I'm running into some results I do not understand. I constructed an example from my simulation code, where I fit a coxph model without frailty (M1) and with frailty (M2) on a number of data samples with a varying degree of heterogeneity (I'm running R 2.3.1, running takes ~1 min).
