model.frame and predvars
...is why I went that
route, but never noted the difference till now (preparing for my course
in Nashville).
Could someone shed light on the rationale for non-preservation?
Terry T.
Simple example
> library(survival)
> lfit <- lm(time ~ factor(ph.ecog) + ns(age, 3), data=lung)
> ltemp <- model.frame(lfit, data=lung[1:2,])
> ltemp
time factor(ph.ecog) ns(age, 3).1 ns(age, 3).2 ns(age, 3).3
1 306 1 -0.1428571 0.4285714 0.7142857
2 455 0 0.0000000 0.0000000 0.0000000
> lfit$model[1:2,]
time factor(ph.ecog) ns(age, 3)....

coxme frailty model standard errors?
Hello,
I am running R 2.6.1 on windows xp
I am trying to fit a cox proportional hazard model with a shared
Gaussian frailty term using coxme
My model is specified as:
nofit1<-coxme(Surv(Age,cen1new)~ Sex+bo2+bo3,random=~1|isl,data=mydat)
With x1-x3 being dummy variables, and isl being the community level
variable with 4 levels.
Does anyone know if there is a way to get the standard error

: Re: coxme frailty model standard errors?
-- begin included message --
Hi, but why we do the difference : ltemp <- 2 * diff(tfit
$loglik[1:2]) ??
Where I can find information about Integrate Likelihooh and null like
lihood??
--- end inclusion ---
1. Basic statistical fact: 2 * difference in loglik between two nested
models = distributed as a chi-square distribution. For coxme loglik[1]
= likelihood...
