Hello, I am running a few simulations for clinical trial anlysis. I want some help regarding the following. We know trhat as the sample size increases, the variance should decrease, but I am getting some unexpected results. SO I ran a code (shown below) to check the validity of this. large<-array(1,c(1000,1000)) small<-array(1,c(100,1000)) for(i in

Hello, I was hoping that someone could answer a few questions for me (the background is given below): 1) Can the coxph accept an interaction between a covariate and a frailty term 2) If so, is it possible to a) test the model in which the covariate and the frailty appear as main terms using the penalized likelihood (for gaussian/t frailties) b)augment model 1) by stratifying on the variable that

Using data from a multicenter study with a parallel-group design comparing two treatments, I plotted each subject's time change of X after stratifying for center: xyplot(X ~ time | center, type="l", panel=panel.superpose, groups=subject) Now I want these lines to take different colours according to the variable "treatment". Any help? Umberto

Hi Folks, I'm looking for a Winamp plugin to play Speex files. On the Speex Plugins and software page the "Winamp and Cool Edit Plugins = Written by Case" link is dead. Anybody knows where else I can find such a plugin? Please can you test any links before referring - I've been also lead to dead links by looking through messageboards that I came across on Google search.

using either one of the following codes: xyplot(X ~ time | center, type="l", panel=panel.superpose, groups=subject, col = treatment) xyplot(X ~ time | center, groups = subject, panel = function(x, y, ...){ panel.superpose(x, y, col = treatment, type = "l", ...) }) I get two different colours for the lines by these colours do not match the corresponding treatment

Hi Shane and all on the list, Thanks - I already have the Ogg Vorbis encoder (oggenc.exe). I am looking to send voice messages to a friend in India and they have terrible connections.

Hey guys, This patch will allow you to include different configuration files in the main dovecot.conf by using globbing [1] (like Apache for instance). !include = conf.d/*.conf !include_try = /etc/dovecot/extra* So with this you can split the dovecot.conf in different smaller configuration files. It's more the debian way to do that. But it's very handy if you have to generate
