similar to: Incidence Matrix of Experimental Design Using R language Program

Dear all, I have a stat question that may not be related to R, but I would like to have your advice. I have just read a medical paper in which the authors report the 1-p (where p is the cumulative survival probability from the Kaplan Meier curve) as incidence of disease. Specifically, the study followed ~12000 women on drug A and ~20000 women on drug B for 12 months. During that period

I would like to compare the incidence rates of three groups. They are supposed to have different risks so I would like to test whether there is a increasing trend in the incidence rates. Does R or any packages provide a trend test for incidence rates? I checked epiR and epitools. It seems they do not have this function. Thank you for the help. -- View this message in context:

Hello everyone, I am a very new user of R and I have a query about the cuminc function in the package cmprsk. In particular I would like to verify that I am interpreting the output correctly when we have a stratification variable. Hypothetical example: group : fair hair, dark hair fstatus: 1=Relapse, 2=TRM, 0=censored strata: sex (M or F) Our data would be split into: Fair, male,

Hi, I want to write own R functions for cumulative incidence function and also for the pseudovalue of the cumulative incidence function. Can you help me? Tas. [[alternative HTML version deleted]]

Hello, I have a problem regarding calculation of Cumulative Incidence Function. The event of interest is failure of bone-marrow transplantation, which may occur due to relapse or death in remission. The data set that I have consists of- lifetime variable, two indicator variables-one for relapse and one for death in remission, and the other variables are donor type (having 3 categories), disease

Hi everyone, I am using the package cmprsk in R to estimate the cumulative incidence function and its variance. In the manual it is mentioned that the variance is calculated based on Dr. Aalen's paper (1978, Nonparametric estimation of partial transition probabilities in multiple decrement models). I would appreciate if someone could provide me with a source where the variance is expressed

Hi, To use cuminc() from cmprsk package, if a subject has 2 events (both the event of interest and the event of competing risk), should I create 2 observations for this subject in the dataset, one for each event with different fstatus (1 and 2), or just 1 observation with whatever event that happened first? My analysis objective is calculate cumulative incidence for the event of interest.

Dear R-community, I would like to plot the numbers at risk for the different causes of failure at specific timepoints below a cumulative incidence function plot (plot.cuminc-function, cmprsk-package). For a Kaplan-Meier plot I know this is possible with the n.risk-argument in the survplot-function (rms-package), but to my knowledge no such readily-available functions are available for competing

All: Though I am fairly new to R, I am trying to work my way through J Oksanen's "Incidence Function Model in R" and can't get past some error with my glm arguments. I'm getting through > attach(amphimedon_compressa) > plot(x.crd,y.crd,asp=1,xlab="Easting",ylab="Northing",pch=21,col=p+1,bg=5*p) > d<-dist(cbind(x.crd,y.crd)) > alpha<-1

Dear all, how can I convert an m x n incidence matrix into an m x m adjacency matrix or an n x n adjacency matrix? The current matrix contains binary data, hence the new matrix would contain counts of common occurrences. Thank you for your help. Phil

Thank you. While I'm currently in the process of migrating to AlmaLinux 8 via an in-place upgrade, I initially wanted to update the base packages on CentOS 7 before proceeding. However, given the circumstances, it seems deploying a separate AlmaLinux machine for testing might be the most efficient approach to troubleshooting the issue. If the problem persists on a fresh AlmaLinux

Hi, I am wondering if anyone can explain to me if cumulative incidence (CI) is just "1 minus kaplan-Meier survival"? Under what circumstance, you should use cumulative incidence vs KM survival? If the relationship is just CI = 1-survival, then what difference it makes to use one vs. the other? And in R how I can draw a cumulative incidence plot. I know I can make a Kaplan-Meier

Hello. R-devel, r61697. I am having difficulty interpreting section 1.4 "Writing package vignettes" of the R-exts manual. Specifically, I want to use system.file() in some of my packages to locate a bib file, uncertainty.bib, which is part of the emulator package. I only want to maintain a single .bib file. R-exts says: "All other files needed to re-make the vignette PDFs (such

I have two versions of a bibtex database which have gotten badly out of sync. I need to find find all the entries in bib2 which are not contained in bib1, according to their bibtex keys. But I can't figure out how to extract a list of the bibentry keys in these databases. A minor question: Is there someway to prevent read.bib from ignoring entries that do not contain all required fields?

Back in 2010 I raised this issue, and there was some discussion, https://stat.ethz.ch/pipermail/r-devel/2010-November/058987.html The goal, then, as now is to have a way to produce a bibtex-clean .bib file (i.e., not requiring manual editing except in unusual circumstances) reflecting installed packages for use in writing where one often needs/wants to cite all packages used in a given

Hello everyone, Samba stopped authenticating AD users after minor upgrade.

I'm working with some people using apple laptops. When we share text files (latex files), I reach in an encoding problem on our CentOS laptops and desktops. In my favorite editor, "?" is "<8e>", "?" is "<88>" etc... Of course, I can change the encoding with iconv: iconv -f MACINTOSH -t ISO8859-15 file.bib.mac >file.bib iconv -f
