Hi Group, I wonder if R has the function CensorReg which takes care of left truncation. I know it's in S. Thank you so much! Kel __________________________________________________ Do You Yahoo!?

Hi everybody, Working with interval censored data using S+, I often use the survival analysis' functions kaplanMeier() and censorReg(). Does anybody know, whether these functions exist in R, too? Thanks in advance for any answer! Saludos, Klaus. ---------------------------------------------------- Klaus Langohr Departament d?Estad?stica i Investigaci? Operativa Universitat Polit?cnica de

I am a student (and very to new to R) working on a senior design project that is attempting to determine the demand distributions for single copy newspaper draws at individual sales outlet locations. Our sales data is right-censored, because sell-outs constitute a majority of the data, and we are also testing the relevance of including covariates (weather, seasonality, economic condition, etc.).

Bonjour, J'ai un probl?me pour traduire "upstream provider" qui appara?t ? de multiples reprises. Je comprend bien ce que cela veut dire, mais je ne voit pas comment le traduire. Merci d'avance.

Dear list, I would like to simulate individual survival times from a model that has been fitted using the survreg procedure (library survival). Output shown below. My plan is to extract the shape and scale arguments for use with rweibull() since my error terms are assumed to be Weibull, but it does not make any sense. The mean survival time is easy to predict, but I would like to simulate

Dear all, I am new to R and may make beginner mistakes. Sorry. I am learning using R to do survival analysis. As a start I used the example script code provided in the documentation of predict.survreg of the survival package: # Draw figure 1 from Escobar and Meeker fit <- survreg(Surv(time,status) ~ age + age^2, data=stanford2, dist='lognormal') plot(stanford2$age, stanford2$time,

So, I abandoned the hope of using the ogg python bindings to do pure ogg container encoding. I started looking at the libogg in the hopes of retooling the bindings to follow a better object model and it actually looks like the problem is down in libogg, not the bindings. Am I crazy or does libogg rely on libvorbis to return ogg_packets, and that there are no functions that will build an ogg_packet

I have been retooling an S4 class definition to include another slot and have found that the methods::validObject function (defined in methods/R/SClasses.R) in R-devel throws an error that isn't caught internally (and thus not controllable by 'test' argument) when retrieving a non-existent slot. The offending line of code is shown below: > validObject function (object, test =

Dear R-experts: I am using survreg() to estimate the parameters of a Weibull density having right-censored observations. Some observations are weighted. To do that I regress the weighed observations against a column of ones. When I enter the data as 37 weighted observations, the parameter estimates are exactly the same as when I enter the data as the corresponding 70 unweighted observations.

Dear List, Is there an automated way to use the survival package to generate survival rate estimates and their standard errors? To be clear, *not *the survivorship estimates (which are cumulative), but the survival *rate * estimates... Thank you in advance for any help. Best, Brian [[alternative HTML version deleted]]

Assuming the price of an ADSI screen phone (say, Aastra 390) was the same as an IP screen phone (say, Cisco 7960) and someone was setting up an * server for their 20 employees (each of whom would have either an ADSI or IP phone on their desk), would there be advantages to using the ADSI phones over the IP phones, or vice-versa? For discussion, let's assume that the hardware needed to

Hi all, Is there an equivalent to predict(...,type="linear") of a Proportional hazard model for a Cox model instead? For example, the Figure 13.12 in MASS (p384) is produced by: (aids.ps <- survreg(Surv(survtime + 0.9, status) ~ state + T.categ + pspline(age, df=6), data = Aidsp)) zz <- predict(aids.ps, data.frame(state = factor(rep("NSW", 83), levels =

Hello, I would like to know if there is a function in R that will test for normality and handle censored data sets. Currently, I evaluate each censored data set by the extent to which a normal scores plot approximate a straight line. For complete data sets I use shapiro.test(). Below is an example of a censored data set. data1<-c(0.00, 0.00, 0.00, 5.86, 5.17, 8.17, 5.12, 4.92, 7.08,

Hello, one of our developers is developing his Web applications (PHP-based+MySql) on 64-bit Fedora. He would like to use the same, 64-bit environment on CentOS. I am not against 64-bits (we use it for many, many years using Solaris) but what concerns me is the stability of 64-bit Linux. Can you share your experience regarding stability of 32-bit and 64-bit CentOS ? Does anybody use 64-bit CentOS

I hope this question is sufficiently different from the other requests for book recommendations that it's not repetitious. If not, I apologize in advance. I'm curious what standard reference books working statisticians, or biostatisticians, have within easy reach of their desk. I'm a computer systems administrator, and have a two-foot bookshelf directory under my monitor that contains

I just re-integrated fixdeleting.rb, the last of the post-processors. Running minimal.rb no longer segfaults on exit. Running dialogs.rb and immediately exiting doesn''t segfault, but bringing up a dialog and then exiting does. So there are still memory problems, but fewer than yesterday :-/ I''m not sure how it compares to last week. I probably won''t have much time
