similar to: implementation of Prentice method in cch()

Dear all, I have a couple of questions regarding the survival:::cch function. 1) I notice that Prentice and Self-Prentice functions are giving identical standard errors (not by chance but by programming design) while their estimates are different. My guess is they are both using the standard error form from Self and Prentice (1986). I see that standard errors for both methods are

I tried to compare if cch() and coxph() can generate same result for same case cohort data Use the standard data in cch(): nwtco Since in cch contains the cohort size=4028, while ccoh.data size =1154 after selection, but coxph does not contain info of cohort size=4028. The rough estimate between coxph() and cch() is same, but the lower and upper CI and P-value are a little different. Can we

Dear all, I am reading the cch function source code. But I can not understand the following codes. Please help me. What's the fitter here? fitter <- get(method) out <- fitter(tenter = tenter, texit = texit, cc = cc, id = id, X = X, ntot = nn, robust = robust) [[alternative HTML version deleted]]

----- begin included message In case cohort study, we can fit proportional hazard regression model to case-cohort data. In R, the function is cch() in Survival package Now I am working on case cohort analysis with time dependent covariates using cch() of "Survival" R package. I wonder if cch() provide this utility or not? The cch() manual does not say if time dependent covariate is

Jin Wang had an error. My original note specified a variable that was 1 for subjects NOT in the subcohort, so the correct coxph call is coxph(Surv(edrel, rel) ~ stage + histol + age + offset(-100*(subcohort==0)) + cluster(seqno), data =ccoh.data) This gives the same coefficients as the cch example, along with the infinitesimal jackknife or "robust" variance estimate.

merci de m'accorder un petit peu de temps ... c'est gentil de votre part ... le service cron que j'utilise est sur PC l'appli doit être lancée toutes les minutes le .exe et le .ini se trouvent sur G, qui est en effet une partition montée via samba sur une station NT si ca peut être plus clair, voici un test que j'ai fait : - test.cmd est un fichier de commande permettant de

I have a ruby program that uses a FXCanvas, and I have attached a FXDCWindow to control it. It lets me draw lines, rectangles and ellipses, but not text. If I attempt to draw text, I get the following error This application has requested the Runtime to terminate it in an unusual way. Please contact the application''s support team for more information. >Exit code: 3 I also get this

Hi, I've had many requests in the past for a Speex DirectShow filter. Well, the wait is now over, thanks to Jean-Francois Emond. Both source and binaries are available from the "Other software" page (http://www.speex.org/projects.html). Bear in mind that for now, only a subset of Speex features are supported (8 kHz, 15 kbps). For those who would like to know what's coming next,

Dear R users I would like to calculate the Cumulative incidence for an event adjusting for competing risks and adjusting for covariates. One way to do this in R is to use the cmprsk package, function crr. This uses the Fine & Gray regression model. However, a simpler and more classical approach would be to implement the Kalbfleisch & Prentice method (1980, p 169), where one fits cause

Bonjour. Ne pouvant pas afficher toutes les pages web avec html window, est-ce qu''il est possible à partir d''un bouton de coller l''url choisi dans la barre de recherche d''IE7 par exemple et d''ouvrir IE7 automatiquement à la page recherchée? Est-ce que vous pouvez me donnez quelques explications si cela est possible? merci sebastien

Hello everyone, please I need your help. To reproduce my problem I created simple pass for backends (TestPass.cpp in attached files). That pass I call from Mips backend in this way (MipsTargetMachine.cpp): bool MipsPassConfig::addPreRegAlloc() { addPass(createTestPass()); return false; } The problem becomes, when I am trying compile file ldtoa.ll (in attached files).
