1. [S] coxph with frailty terms: df's for LR tests (score: 1)
Author: Ramon Diaz-Uriarte <rdiazuri@students.wisc.edu>
Date: Thu, 8 Jun 2000 10:09:12 +0200
Dear All, I have some coxph models with frailty terms. These are nested models, and I often want to test for one or more factor terms with more than two levels. I thought the way to go was to use lik

Dear All, Suppose I have a factor (say, three levels) in a model fitted with coxph (or survreg) that includes a frailty term, and I want to get a p-value for that factor. This is what I thought I sho

5. [S] survival analysis with several random effects (score: 1)

Dear All, I would like to analyze repeated (or multivariate) survival data, when there are several levels of "random effects" (e.g., location, month, and individual; location and month are crossed).

That happened to me too; I fixed it doing: frailty (..., sparse=F) I found I needed to do this in all frailty terms except the last one. (Note: I did all this in R). Ramon At 10:18 AM 3/22/00 +0100,

I must be (partially) part of that minority too: I like manuals/books that introduce you to and explain how to use the software (e.g., I found it very useful to read, kind of like a novel, the progra

I would like to change the width of lines in some plots, but the "lwd" argument to functions such as lines, segments or plot.survfit only works when lty=1, not with other line types. I am using SPlu

Hi Ziv, It was my understanding that there were still some problems with frailty models; I guess I am missing something important? However, while waiting for survival5, there is a set of programs, "T
